How to Calculate Molar Mass Practice Problems
HTML-код
- Опубликовано: 16 апр 2014
- We will learn how to calculate the molar mass of a compound by using its chemical formula. Molar mass is a quantity that is very similar to molecular mass, molecular weight, formula mass, and formula weight. In order to calculate molar mass, we look at the formula to determine how many atoms of each type are in it, and then look at the periodic table to determine the atomic mass of each of the atoms. We will look at compounds containing polyatomic ions, and also hydrate compounds.
Can I just say, you are an amazing teacher. You make Chemistry look so easy.
that's because it it... your little mind and conscious just make it difficult. nothing is hard if you dont make it.. things are what you make them to be.

Azqui it not, but you could make it if you wanted to...Your choice.

I got an A+ on my last chemistry test from watching your videos!!!
in which class are you?
+اباذر كاظم ch...chemistry
ur hot in ur youtube vids
thanks I got A+ in my test and I love I nepal
I have a final tomorrow I hope these help me too c:
I love you, I love you and I love you!!!!!!!!!!!! I can't believe I was about to quit my chemistry class until I watched your explanations. You saved me from my frustration and from that man who calls himself a professor. My professor is horrible I never understand a single material he teaches in class. All of your videos have been saving my neck, day by day. AGAIN, I LOVE YOU! God keep blessing your intelligence and capacity to explain chemistry.
I totally understand!
how are you learning this in college/uni
Tyler I've recently been diagnosed with ADD and have always had trouble learning stuff and focusing. Thank you so much for making this so simplified for students.
You are GOD GIFTED, Literally !
so why the pentagram?
XD
@@callmetired2294 ikr
the 171 people who dislike this video is all of our chemistry teachers haha
😂😂
Lmao
That's why RUclips removed disliked
😂😂😂
😂😂😂 hahaha true
This was explained to me so many times and I got it in just minutes from watching this video, talented teacher.
You make chemistry look easy. I look at my book and don’t know what I’m reading, but listening to you explain makes it so much easier. We all appreciate you 💗 you’re going to get me through all the chem I need to take in college. You’re a life saver!
A got an A on my CHEM test last week thanks to you Tyler. Now we are moving to Molar Mass/Mass calculations.
Yeah I'll def be passing my chemistry test tomorrow xD thanks mayn
Me too. My chemistry teacher doesn't do shit and the test is tomorrow. Now I might get a good grade.
saaaame
Did u pass?
Same bro
@Softboii Tingz oh yeah im like a chemist now bro
My classes are an hour long and I don't understand a word my teacher says, this man explains it in 12 minutes and I understood everything. Gods gift I'm telling you!
Hey! It's been quite a while since you've uploaded but I would just like to thank you for contributing all of your videos. My chemistry teacher has been using them alongside his lessons to help us better understand certain concepts and I find them very helpful. I'm interested in chemistry and I want to continue with it into postsecondary so I'm thankful to have been shown your channel :)
wait a second wait a second...my chemistry teacher is named Dewitt...he always talks about his son...and he has shown us these videos. I've never noticed until now, but, are you his son?
Spack Jeeka lool I'm dead
and the plot thickens
@@shouryaseth5715 indeed it does.
If that’s so ...wouldn’t the father (Your teacher) be smarter than the son and teaching the son chemistry if that’s the case why are you here ... and the plot thickens
soooo? is he the father?? still in suspense after 4 years
Your way of explanation is amazing.
I CAN FINALLY PASS CHEMISTRY THANK YOU
you have the BEST way of explaining and saved my grade in chem!! thank you!!!
There is no way i would get through my chem without you!!
I want to thank you for all the help that you have given me. I have a test coming up this week and your teaching lectures have really showed me how to solve the problem step by step. May GOD bless you and your family always keep up the good heart of helping others in need
I learn more off this than my teacher
The Final Calculation Of MgSo4.7H20 is wrong in this video.
The correct answer is 246.52 grams per mole
I was getting confused thinking why mine is 246.52 but his is 246.46? And i worked out again and again but the same 246.52
Aditya Mane thank you! I thought I was doing something wrong-still love your videos!!!
Thank God someone said it, I was breaking my neck trying to figure out why my calculations were incorrect
Oh thank god i kept thinking i was doing it wrong
i was wondering if anyone caught this too!
I’ve learned more in these 13min than I have learned I and entire 1hr class
Tyler DeWitt=Reason I'm going to ace my exam today. Thanks!
please keep making more and more videos. your the only way i can actually understand and ENJOY chemistry :) thankyou so so much!
You honestly have a gift 6 years later and I found ur video. I haven't understood a thing for the past 2 weeks, one video in and it all makes sense
You are the besssst!! I have been watching your videos all day because I have a test tomorrow and now I feel much more confident. I didn't understand anything because I had a bad teacher but now it is super clear. Omg thanks so much!
you taught better than my teacher .Thank you brother
BEST TEACHER. And not for chemistry but just period. You are so transparent, straight forward and don't complicate things. You should give a class on how to teach other teachers how to teach.
My online/hybrid chem teacher is THE WORST AT EXPLAINING ANYTHING. Learning everything from your videos. Thanks for being my chemistry professor.
Thanks this was really helpful, i was struggling so much in chemistry
You helped me big-time in my exams Sir!!! THANK YOU AND CONTINUE DOING THIS!!!
Your enthusiasm for Chemistry is highly contagious! TRULY wish I had you as my high school Chemistry teacher. I think I may have not only succeeded (which I didn't back then) but also learned to enJOY Chemistry!!! Thank YOU for posting these videos!!
can anyone give this guy a medal .... thank you sir
YOU ARE AMAZING BRO ... I CAN UNDERSTAND MOST OF EVERYTHING BECAUSE OF WATCHING ALL THIS VIDEOS EVERYDAY AND NIGHT KEEP IT... BLESS YOU
You are brilliant and a wonderful teacher! Thank you for the work you put into these.
just registered on youtube to say thanks. the best teacher i ever had
Not even khan academy was able to be specific on what Molar Mass is. And here you explaining o SIMPLE. Subscribed.
So glad I found your channel! I'm a visual learner so how you place everything out has helped me a ton! quick question when I did the last calculation for MGSO4*7H2O I got 246.52g/mol.. Is it ok to be off by a bit like that?
24.31+32.07+64.00+14.14+112.00= 246.52...Or is there something I did wrong?
SteppiV i got 246.52 also
He calculated it wrong it is 246.52 grams/ mole (wish me good luck for my science exam tomorrow!)
+SteppiV yeah ur right.. same here..
Whew, I'm not crazy! lol
lol, I redid the math like 5 times
Yay, you're back making videos ^-^. I like the other chem teachers on socratic, but in my opinion, your videos are more enlightening and clear =).
@Ernesto M. ??????
I can't even begin to describe how much this guys videos have helped me in my studies. So grateful!
Thank you so much or making these videos Tyler! I have and will continue to watch just about every single one you have. I'm in a two hour chemistry lecture class two days a week and walk out of there not understanding a thing, but when I come home I watch your videos and the material is crystal clear! THANK YOU THANK YOU THANK YOU!!!!
These vids r soo good i can understand them soo easily
up at 12 doing a project rn and learning this from you is so easy 😂
bro seriously, you're killin it.
NEVER SEEN BETTER EXPLANATION THAN WHAT YOU DID !
OMG!! I am so glad I found this channel!!! You are a true hero!!
As an eighth grader who is currently flunking science, I thank you
It was easy, clear, and understandable lesson. Thank you.
One thing I never understood is how will I know which is which? Like how would I know if It's OXYGEN or Sulfur that the 64.07 grams represent, HOW WILL I KNOW PLZ SOMEONE TELL ME.
I get so elated when I search up a chemistry problem question and find a video you've made on the breakdown of how to solve them. I'm a visual learner and your videos are great!! I get so confused in my morning chemistry class but after watching your videos, it makes it so easy and simple!! Can't thank you enough!!
Wow if only all teachers could explain this like you. Thank you. I would be lost in the world of Chemistry without your fab explanations and visuals. Don't stop!
Like Ece Zongur, I also got 246.52 grams/mol for the final calculation.
SIR,DO YOU TEACH PHYSICS ALSO?
i wish he were
I should pay you instead of my teacher. the only thing he does is mess my head after I learned with you. I cannot thank you enough. you have a gift in how to teach. Many blessings to you :)
Thanks! Love how you explain things in a simple but clear way.
so simple, its perfect
omg can i just say that you are soooooooooooooo good wow
You're the best!!! My chem teacher gave us our midterm grades for the summer semester. She said my projected grade is an A+. Your videos have helped me a lot. I can't thank you enough.
Thank youuuuu! I haven't taken chemistry in 4 years, and I didn't take the prerequisite class for my chem class this upcoming semester. I now have to take a placement test to be able to fully enroll in the class. I've been binge-watching your videos, and they're super helpful!
YOU ARE THE REASON WHY I GOT AN A ON MY FIRST EXAM, HOPING TO DO THE SAME ON MY SECOND! #CHEMHERO
wish me luck tomorrow!
Hey man I just wanted to say thank you for explaining these (difficult) things in a way that anybody could understand, thanks to you, I feel very confident that I will pass my chemistry midterm exam.
Dude, you are amazing. I finish chemsitry courses in school 10 years ago and so even though I did them, I do not remember a single dang. Now when I decided to study in uni, your videos are like a blessing. Thank you so much!
literally came from so many different places and i still didn't get it till now
ikr same, and your username has me living
the answer for Mg SO4*7H2O is 246.52g
Thank you! Thought it was just me and I was going crazy!
I find the method of teaching by Tyler is BEST so far.
I'm so glad I found this video! The way my teacher explained was very confusing, but when you explained it, it made perfect sense- One of those, "Wait that's all there is to it?!" moments. Thank you!
I got 246.52 in the last problem did I make a mistake or what?
I thought I was the only one. I had to check if my calculator was broken or something.
Oh well, people make mistakes. Even if it's a cool and awesome teacher like him :)
Round it off 246 is the answer
yeah you have the right answer but this man is teaching amazingly!
Online class people rise up
thank you so much for making these videos! your short videos help me understand better than sitting in a classroom for a week and not getting anything. THANK YOU
GREAT!!!!! I am truly happy people like you exist!
Who is here he because the where confused asf in school
I learned how to do this on my own haha, balancing and common sense played a role, i remember sophomore year in a pop quiz, i thought i was going to fail but fortunately didn't
dude, u explain concepts so good that i understand it in the first time
You are the best teacher I have met so far. Good job. Keep it up
i cant get over this guys lanky furry arms
lol me too
corona virus brought me here
Love how much effort you put in every videos to teach people. Now i pretty much understand moles that has been taught by you in a few videos than my teacher which has been teaching me for a couple of years!
Thank u so much! You don't realize how much this helps me! You are a great guy by helping out needy students suffering from ignorant chemistry teachers now a days! God bless :)
I appreciate how you don’t rush through concepts and give plenty of examples.
I'm just there in class with my eyes glazed over. The professor's a nice lady but nothing she says sticks in my brain.
Thank you for explaining each step clearly and easily. The visuals were greatly needed.
sir i decided to watch ALL of your videos because I know you are the best chemistry teacher one can ever have.
your videos are absolutely amazing! i recently just went back to college after not being in school for 8 years so chemistry is all new to me and your videos are such a huge help! thank you so much for sharing these! you're great!
You are the best teacher ever!!... 🤗🤩 hit like if anyone agrees with me
Seriously, I'm 12 and I'm watching this, and now thanks to Tyler now I know what molar mass is...
Your videos are so clear and easy to understand, I'm glad you are back making them. They are so helpful with my A level chemistry. Thank you
Wow all I have to say is Thank you!!!! I am 44 years old, going back to school.I could not comprehend this when I was in high school. Now because of you I can.
Thank you so much :-)
Well done for going back to school!
I just wanna let you know that you deserve everything in this universe.. thanks alot for the lessons!
Thank you so much for making this, because of this video I was able to avoid a mental breakdown. I had studied chemistry all day and couldn't figure what was wrong with my formulas, thank you thank you thank you!
you are one hell of a teacher !! trust me,you've got some serious teaching skills
I'm not joking. Every time I don't understand Chemistry, I watch your videos. Thank you!
You are by far one of the best Teachers I have ever come across. It is your to be be a teacher!
Thank you so much for making Chemistry actually understandable!!!!!! You are such a blessing!!!!!!!!
Tyler,
We all Appreciate you very MUCH
Respectfully,
everyone who thought they were going to fail chem until we found Tyler!
You are great at explaining this stuff! Thank you so much for your videos!!
Your videos are really helpful! I don't think I could get through this chemistry class without your videos so I had to say thank you! You do such a great job of teaching a confusing subject in a less complex and more understandable way!! Everything I learn in my class and by reading the book is more confusing! Your ways are much easier to understand, remember and use. It is unbelievable the difference your videos make!
tyler DeWitt you are amazing idk what i'd do without your videos keep it up the great content !
The way he teach make me feel like I hate Chemistry less now because the teacher that we have don't know how to reach students and seems like the teacher doesn't care how much all students will get from the class.
Tyler made it so understandable. Keep it up !! you the best:)
I am confident on my test today. You really helped me get through Chemistry this semester. Thank you!
I've seen a lot of chem instructional videos on here and I must say, this guys the best.
This dude is phenomenal, he starts you off with that mind set that you will be a pro, then proceeds to explain EVERYTHING, this man doesn’t assume you know stuff.
الف شكر ع المجهود الرائع................
...........thank you very much
I have just discovered your videos, and Im extremely dumb at chemistry, so Im beyond grateful for this video, bc it made me understand the whole thing which is molar mass. Thank you so much for this content.
