I HAVE AN EXAM IN 2 HOURS AND CRAMMING RN, LAST NIGHT I WATCHED THE CHEMISTRY 52 MIN REVIEW, YOU DO NOT KNOW HOW MUCH THIS VIDEO WILL HELP ME FROM A 50 TO A 70, AND THE FACT I HAVE MORE MINUTES BEFORE THE EXAM TO WATCH MORE VIDEOS... THANK YOU SO MUCH, NEXT TIME I KNOW HOW TO BE MORE WISE WITH MY TIME BUT YOU HAVE SAVED ME FR
can we already give this guy an award? my teacher is about to give up on me because I can't get what the mole concept is nor the words he is saying. And this guy already finished it in just 18mins.
Bruh this man's a legend. I didn't understand anything about moles, but this video was like a light at the end of the tunnel. I can actually understand it now.
@dizonjamesmulenga7260 still nowhere near as smart as this guy but 4 years later and I can at least say I became a organic chemistry tutor while I was in college lol
You’re an amazing teacher. I wish these videos had been around when I was in school the first time. I have learned more from working out the problems as I watch your videos than from the classes I’m actually enrolled in. Thank you!
In around the 8th minute, the formula unit should be 2.4x10^24 and the no. of Cl ions should be 7.2 x 10^24 as you add one unit of exponent when you move a decimal point to the left
Dude you are a literal life saver my chem teacher doesn’t help me and he never answers any questions you are so awesome thanks i appreciate so much what you di
Because of my up coming exams, I spent a whole hour trying to finally understand this part of the lesson in chem and with the help of this video I am gradually able to understand it more now.
Professor Organic Chemistry Tutor, thank you for an outstanding focus on Avogadro's Number and its usage in moles to grams and grams to moles conversations/calculations in AP/General Chemistry. Avogadro's Number is important in all levels of Chemistry. Professor Organic Chemistry Tutor, thanks to the viewers for finding and correcting the error(s) in this video.
Thank you so much for this legendary video , really cleared out all my paranoia regarding molar calculation as i start my first semester of college with Chem 130 classes after a gap year!
i got a question. at around 14:55, he didnt finish calculating, why did he skip the actual calculation, and went straight to converting moles to atoms?
The explanation of Avogadro's number and molar mass is the best that I have seen. Great job. There is an error at about 8 minutes. Should be 10^24 not 10^23. This is minor issue - just pointing it out for others in case they notice it.
i'm literally so dumb that i still don't understand. like i really don't want to fail. my physical science class is the only thing i'm failing and it's with a low B. everything other class i'm passing. i hate online, it's so hard.
You’re not dumb man. School makes a lot of people think that about themselves but they judge your worth in grades solely and not talents and things you excel at. So don’t worry about it. Grades are important but you are not dumb if you have bad grades
1 (unit).mole of a compound Weighs the molecular weight of the compound, in (units). E.g. 1 gram.mole of Oxygen (molecular weight 32) is 32 grams. 1 gram.mole of any gas at Standard temperature and pressure (stp) occupies a volume of 22.4 litres. It will contain N (Avogadro's number) molecules 6022 x 10^20 This has been found to be physical fact Molecular weight is the combined weight of all the atoms in the molecule. Atomic weight is weight of the substance atom, compared to a Hydrogen atom. I.e. the density of the gas compared to density of Hydrogen. How many times heavier it is. Lack of the above knowledge is what leads to the Endless Boloney and confusion which this teacher so perfectly demonstrates.
I've learnt that m = n x M and n = m/M are formels that you can use when you want the mole mass, mass or the amount of substance. For example: Calculate the amount of substance for 750g propan. Propan= C3 H8 12x3 + 1,01x8 = 44,08 750/44,08 = 17,01 g/mol Also I understood the video very well!
Deep THANK YOU for all your work! You have been very helpful. People like you making free content like this are the leading edge of education today. My university lectures aren't as clear, concise, accessible and engaging as this
Hey man, you are a genius! You can't imagine how simple you make these calculations look. Lots of love all the way from Nigeria. I have recommended my friends to this channel. Thanks so much!!! 🙏🙏🙏
This video was amazing. It was the best video I have seen on the topic. There is a math element that is set-apart from other videos I have seen (which rely heavily on calculators, which belch out digits, with no mathematical accountability, nor understanding), that I can really appreciate, as it will carry into other subject areas, and serve me well, moving on in chemistry. Your presentation was lucid and just...perfect.
You are an amazing teacher. I wish you were my chemistry teacher. I also advice that after teaching, you drop two attachments(links): one related questions alone and the other, the solutions . This will help the student test him/herself and get better understanding.
You dont know how much this helps me. Its been 28 years since i took gen chem and organic. Now i basically have to make my own medical device (for me and the world).....ive got access to the laboratory but i have to run the experiments, which means i need these calculations ! Im subscribing right now.
idk if anybody is going to respond to this, at 7:45 wouldn't it be 2.4 x 10^24? To my understanding the 4x6 got 24 and then you move the decimal one space to put it into appropriate scientific notation while the initial notation was 6x10^23.
Thank you agin for your videos. I rely on them for every chapter as I study Organic Chem. I wouldn't be able to understand O-Chem w/out your help! You are fantastic!
I have saved this video because I`m sure this is gonna come in great use... Keep it up King! I understood most of it and I`m gonna watch it again to understand it better next time. You help many students understand Chemistry and other subject so much easier and you deserve an oscar for that bro.
Thank you for making sense of this for me. We have no lecture as apart of my online class, and its hard for me to just read something and get it. Even with examples!
Thank you so much for this video as class is fast paced and I often struggle to keep up. My professor has never broken it down in such a clear and straightforward way!
Thank you so much for thiisss. I watched this bfore my classes starts bcause my prof said were going to discuss formula /molar mass this meeting. Damn 17 minutes vs 2 hrs of lecture 😂 Thank you again, i understand it 100% ♥️ Always saving us
Thank you so much! Im learning this crap in middle school and it is such a pain its so annoying. My teacher didnt teach me anything but this just helped me like 69x more than my teacher did.
Hey at 7:43 did anyone notice that he forgot to change the 10 to the 23 to 24, I just had to say it, for people that are not sure, but then the final answer would equal to 7.2 ×10 to the 24... we all make mistakes it's only human, thank you so much though, you've taught me so much....and to the students like me, you'll make it just put the time and grind, love you and take care
but if you multiply 2.4x3 you are already given a decimal answer which is 7.2 It was already in decimal form, you only ad +1 in 23 if the answer wasn't in decimals.
In the beginning of the video you said that the value of the mole is *6.02x 10^23 but it should be 6.022x 10^23!!. as mentioned in our book . Even I searched in the web and got the answer as 6.022x10^23*.
i need a teacher like youuuu. hmm even im at uni now but still i need a slow teach and very deep explanations . but all the lec think we know all they dont need to explain further, hmmm. thank you for this, i watch your video since im in pre-uni until now im in university. God bless keep doing this, i need did. thnk youuuuuuu :) ♡♡
I have been trying to learn this concept for weeks now, and somehow you taught me this in 20 mins when my teacher hasn't been able to teach this to me this in the time that we already have an exam coming up on it, so thank you🙌
