I love how you talk like you are asking yourself and/or teaching. Instead of talking to us like we should already know this and skip steps. In fact you do the opposite. You teach us as if we are new. I thank you for this and please not stop teaching us like this. Thank you once again.
The best textbook *by far* is Maitland Jones' Organic Chemistry, which goes step by step and explains the reasoning behind all the reactions, so you're not just memorizing a bunch of stuff that doesn't make sense. I haven't found many great online resources. Khan Academy isn't very good for Orgo (in my opinion) but, you know, it's there and watching it can't hurt.
The order doesn't matter, because they're all multiplied together. n*R*T = n*T*R, just like 2*4*3 = 2*3*4. When you have a question like this next time, try it yourself in the calculator and see if you can figure out if it affects the outcome on your own. I'm happy to answer these questions, but there's a lot you can learn by yourself.
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
If all chemistry teachers were as good as you are, i doubt that we'd be online searching videos :) Keep up the good work bro and thank you for your help
I love your videos, it literally saved me from failing the tests. I watch your videos after every class of chemistry, my teacher is very bored to explain the steps most of the time, and we are always left with question marks after. But I'm happy to come home and watch your videos going through the steps and to be able to understand it better since you make chemistry seem so easy :)))) Thank you !!!!!!!
I've been watching all your videos non stopppp X'D My test is tomorrow yet I did revision last minute and guess what? Your videos saved me! Thanks a lot!!!!!!!!
this is so helpful, you go through all the step at a slow speed that lets everyone keep up and you explain everything in every video making your videos so helpful! than you so much you helped me so much!
i know you made this in 2011 but your content is still relevant and extremely helpful. i really struggle working through the steps on my own in my head but i'm trying my hardest to learn. i wish it came as fluently to me as it does my teacher. good thing im going to art school.. just wanted to say thank you!
Tyler you are are an excellent chemistry teacher. You made every topic as easy as ABC. Please can you make a video on limited and excess reactants. Cheers!!
This an excellent video, really clarifies the topic. I was hoping that you could make a video of gas stoichiometry with a limiting reagent problem. It would be so helpful. Thank you!
What if you are given liters 24 liters of N2, 75 degrees C and 2.30atm, and we're asked to solve for grams of NaN3, instead? Would you plug liters in as V, into PV=nRT and solve for moles (n)? The do a mole:mole conversion between N2 and NaN3....then convert moles of NaN3 to grams?
When you were doing the ideal gas law, it was v=nRT/P, but when you plugged in the givens, you changed the order to v=nTR/P. Does the order matter? Will it change the outcome with your calculator? Thank you. :)
Suppose the teacher tells you length never changes but sometines he says the length is 36.0, other times he says it is 3.0 and sometimes 1.00. Are they the same? Yes, because 36 inchs = 3 feet = 1.00 yard. 0.8206 (mmHg)(liters) / mol K = 8.31 (KPa)(liters) / mol K
So in the problem would you put 24.5 in the bottom of the equation or what would you put at the bottom of the equation cause I’m just super confused on why you didn’t put it all back into the equarion
I think it would make more sense to round based on the data given in the question. Since 75 degrees Celsius was measured to 2 s.f., how can your answer be more accurate than that? Regardless of converting to kelvin. You're converting a less accurate measured number to a more accurate number.
Imagine: There is a mercury-based thermometer that measures up to the equivalent of 1 kilo-Kelvin (1000 Kelvin) with marks every 0.010 kilo-Kelvin (impractical, yes--but bear with me). One finds a temperature reading of 0.348 kilo-Kelvin, and thus it has 3 significant figures. For the purposes of modern society, however, the person converts it to kilo-degrees Celsius, and subtracts 0.273 kilo-Kelvin. The resulting value is 0.075 kilo-degrees Celsius, and since subtraction was used, we still have 3 significant figures, with the 0 after the decimal point holding a significant place, even though it wouldn't under a normally-measured circumstance. Wishing to make the value more understandable to most people, the 0.075 kilo-degrees Celsius is then converted to 75 degrees Celsius--and since this is a simple conversion of the same unit, the same number of significant figures would carry through--so you would have 075 degrees Celsius, all digits significant, but it would be written as 75 degrees Celsius. I hope that made sense! It is very confusing, and I'm not used to teaching or explaining, but I tried.
Your analogy was terrible hahah, but I think I followed what you're saying a little: It was converted from kelvin to degrees for simplicity, the sigfig didn't change but due to the rules of sigfig we aren't able to keep the 'accuracy' (is that the word here?). But another question arises, how do you know this background information from the question. Because with this logic -- can't every data value be treated in the same way even without prior information, how would you ever answer a question if so?
If the temperature is in celsius or fahrenheit, it is always converted to kelvin when we're talking about gases. In this case, 273 was added to 75°C to make it into a kelvin temperature

An entire quarter of struggling and stress solved in 11 minutes. Thank You.

That moment when this guy teaches stoichiometry better than my chem teacher
+Darrien Smith Productions Seriously bro
+Darrien Smith Productions Welcome to america
Tyler is amazing. I watch his videos all the time, and they are truly helpful. I hope he keeps on teaching.
I know I’m 7 years late but this is amazing. I have a test in Gas Stochiometry this Friday and you’ve made everything so much clearer
Lol, 4 years after you and now I have a test for Gas Stochiometry tomorrow
@@andreaaddicott7133 lol 5 months after you
another 6 years making it 12 years later for me
you saved my life. no skipped steps or anything. thank you.

Tyler Dewitt and Organic Chemistry tutor is the reason why i passed chemistry
Tyler,thank you very much.Its been very useful and i have got my fear of stoichiometry out after watching just these 2 of your videos.
LOVE THIS GUY, HELPS ME WITH EVERYTHING FOR MY CHEMISTRY CLASS
BIG GUY lol
Way better than my chemistry teacher! Thanks a ton! ^___^
I wish you were my chemistry teacher when I was in school.
David Miller lol
I can't thank you enough for these videos. This stuff is now SO simple.
really appreciate how thorough you are with each step of the process!
U R AMAZING, TYLER!!!!!!!! My teacher's been blabbering this topic for weeks. Thankyou.
I've been watching all your videos non stopppp X'D My test is tomorrow yet I did revision last minute and guess what? Your videos saved me! Thanks a lot!!!!!!!!

stoichiometry has always been a stumbling block, but this just makes so much more sense! thanks a bunch!
Very nice it has made calculation simple in gas stiochemtry
Excellent explanation, thank you!!
I think you might be Jesus reincarnated... with the sole purpose of helping kids pass Chemistry...
Tate Asher he is
This man is truly better than all others
I feel like any other teacher would confuse this to absolute chaos. Thank you for explaining it so well 🙏
seeing this the night before the test is amazing bro.
Thank you so much!!! I love how much effort you put into your videos! They are so worth it:D
Tyler you are are an excellent chemistry teacher. You made every topic as easy as ABC. Please can you make a video on limited and excess reactants. Cheers!!
you are THE BEST chem teacher!!!!!!!!!!!
This is one of the most helpful videos you have ever made.. Thank you so much!
Thank you sir you are genius in teaching chemistry. coming out with easy way of doing chemistry for kids. May god bless you sir.
Litterally just passed a chemistry test because of you, thank you!
Thank you very much, you saved my exam day
Greetings from Libya ♥️♥️
You're videos are a big help.Keep posting.God bless.
At 7:16, instead of saying 75 degrees, Tyler said 65 degrees.
But except for that you r the best chem teacher I have ever seen
Once again, Thank you so much for doing this.. I don't even know if you will see this, but thank you either way
Thank you very much for this video. I'm designing my own lab and didn't even know what formula I needed before watching this.
tyler ,you man,deserve a prize?God bless u
i've watched all your videos that i needed to watch for my exam coming up haha without this id be failing
You make everything seem so much easier than it really is. What college did/do you attend? It is now my dream college.
thank so much!!! for all your video because of you I'm actually getting an A in my chemistry class
Thanks, I enjoyed your method of approach. Extremely informative and I feel that it promotes viewer creativity.
I am learning this in school and i found this video very helpful and i apprechiate you taking the tim to make it.
This an excellent video, really clarifies the topic. I was hoping that you could make a video of gas stoichiometry with a limiting reagent problem. It would be so helpful. Thank you!
Thank you so much I have been stuck on this for hours and using the steps you took I can finally finish some of these problems
You are a saver!!!!! God bless your efforts.
U should need something for xmas. Thank You
Thank you soo much! I have an exam tomorrow and he said this same chemical equation would be used for a gas stoichiometry question!!!
You just rescued my gas laws test!!
In 4 hours im writing my final exam and I can easily say I'm ready 🙂 , all thanks to you Sir 🙇🏿♂️🙇🏿♂️
Great tutorial! AP Chemistry FTW!
Very helpful and easy explanation. Thank you very much.
Great video, thanks for helping me understand it with ease
BETTER THAN MY TEACHER I LOVE YOU
Thanks a lot bro I really learning may God continue to bless you
You are a very good teacher. My chem teacher is 15 to 20 times worse than you. Thank you very much :) I might actually pass her class now.

I am so happy , i figured how to solve the problem
The morning of my grade 11 chem exam. Thanks !
also same lmao
I was done mine from time now. But thanks!
cool! How did it go?
Another great video, thanks alot.
This was really helpful! Thanks a lot!
thanks Mr. So Detail
Best explanation 👌
This is masterpiece! Very helpful, tysm
Thanks you so much for explaining this so well. I really appreciate it!
Thank you. this helped so much !! tbh teaches alot better than my chem teacher :
I would pay for this man to be my chem teacher
ALL HAIL LORD TYLER, SAVIOR OF STUDENTS.
Love you, dude. :D
I LOVE THIS THANK SOO MUCH. KEEP DOING MORE VIDEOS

0.8206 (mmHg)(liters) / mol K = 8.31 (KPa)(liters) / mol K
Thanks this helped make it easier
why did you use the P and T in PV=nRT when the P and T are given in NaN3 and not in N2?
So in the problem would you put 24.5 in the bottom of the equation or what would you put at the bottom of the equation cause I’m just super confused on why you didn’t put it all back into the equarion
I love this man
Thanks! You helped me a mole lot
This is amazing!! Thank you!
Thank you, that was helpful
How did you get the R value - the constant?
gonna ace that chem test tomo.
Thank you, appreciate this
Big help, thanks
Just saved my life!
where did u get 0.0821 L?
Bro...Thank you!

Thank you
thank you so much! really helpful
great help, thanks!
From the equation PV=nRt. How did you got 0.0821 L.atm? where is it came from? I got lost in that.
Can you tell me how many grams NaCl do we take from 11,5 g Na.And how many liters Cl we need in this case
please do one with limiting reactants! i'm completely stuck!
Vote for Tyler DeWitt as head of the Department of Education. PLEASE.
Why is the R constant 0.8206 wasn't it like 8.31???????
How did you get R? and how do we know to add 273 to make the kalvin? is it always going to be 273? I don't understand! help!!
If the temperature is in celsius or fahrenheit, it is always converted to kelvin when we're talking about gases. In this case, 273 was added to 75°C to make it into a kelvin temperature
You're amazing
