Chemistry Lesson: Molar Mass

THANK YOU VERY MUCH U HELP ME ACE MY TEST!!!!

I don't understand how you got 2.08 for number 5

Take 713 grams and divide it by 342.17 g/mol. 342.17 being on the bottom of the conversion means you must divide by that number.

honestly, you saved my life.

Good chemistry saves many a life. ;) Thanks for the encouragement!

i love you

Thank you so much! I missed a few days of school and this is getting me back on schedule! You are such a great teacher

teacher explains, not understood, show up to the test 3/7 watch your save my life mole trilogy, take the second test about moles 6.5/7.

forgot to mention, thats more than enough to convice me to subsribe

This is so clear , so grateful you put this on to help. I hope I get a good grade on my test!

Let's just keep this between us or my wife might get jealous. ;)

Thanks for the kudos, Amanda! So glad you found this video helpful. Be sure to subscribe to be notified when new lessons are posted!

Awesome! Glad you kicked butt on the second test! Way to go!

I wish more people in my class would watch these! They are so helpful!

You're very welcome! Best wishes on your test. :)

Spread the word and perhaps they will! I appreciate the encouragement and help in letting others know where to turn when they need help with chemistry. Thanks again!

I got a good grade on my test! Thank you very much!!! I learn a whole lot from your videos. They are such a help!

our chemistry teacher is german but he tries to speak english. No one understands a thing. But then i watched this video and now i understand this!! Thank you so much!!!

i need help . i don't understand Example 4 and so on

I don't really understand why the atomic mass of an atom is equal to its molar mass?

How do i give you guys money.... i love what you have done for my understanding in this!!!!!

Omg please be my teacherrr !!333

thank you so much sir!!

My periodic table is different 
like i have the oxygen 16   and the Fe is 56 
will it make a difference in the exam 

Oh... My.... God. You don't understand how much you've just explained how easy this is to me....I struggled for almost two semesters getting 60s in pre-AP Chemistry as a sophomore. I thought i was stupid but no one had explained it like this, my teacher is to side tracked and does this "rail road" track method I was confused on but i learned everything i need to pass with you guys, THANK YOU.

so helpful!!

Hadn't taken Chem in 3+ years... I am now taking Gen. Chem I in college and my instructor refused to teach how to do conversion again saying we should just remember it and yelling at us when we asked questions about it. Thanks so much for the video. Hopefully with the use of these videos I can pass this class.

Thanks so much, my teacher doesn't teach these lessons nearly as well as you do!

That video is great!! Can you please give me some tips on how to better learn chemistry? I am going to take IB Chem mext year... Thank you!

Im here because my teacher forced me to watch you video, but I found your voice very soothing, so thank you.

you saved my chemistry mark! i got 58 for last sem. i will get better mark after watching your videos. 😀

Thank you so much for this!!!

thanks man

thanks so much... test in 2 days

do you have a skype name if u do i hope you'ld tell me ur name so u could explain me another thing !!!

but on this video i've understood everything!!! u've made it soo.much easier the teacher didnt explain it as good as you !!!

again !!

Thank You,
Sameer Rabih

I thank God for you because my teacher....... no comment

After scouting more than 10-15 videos on different sites, yet i could not understand Molar Mass & Mole, however this video has cleared that doubt in the first statement and the table. Thanks Sir I am 46 years old and only understood this after i heard you. I am grateful...........

Hydrogen's Atomic Mass id 1.008. Save rounding oil the end. It gives you an answer that is more accurate!!!!

Thank you so much, this is explaining everything so easy !!

you have done a great job ......(Thanks)

Simple , sweet and crisp . Love it

what about for finding the number of atom of an element in a formula?

I Want To Meet You!!!!

Best video on explaining the mole and molar mass!!!

Thank you for these lessons. I am 44 and trying to get back to high school with distance learning on my own so having these videos are a big big help. Very Much appreciated Dr.

But how did we determined that it's in 12 gm of carbon and 24 gm of magnesium that will have the same number of atoms this could have been 24 gm carbon and 48 gram magnesium that contained same no of atoms. What is the history of determination of atomic and molecular masses.

Thanks so much! I missed a few days of chemistry class as I was sick and this got me back on track!

This is awesome! Now I can make that blue meth I've been working on. ;)

The MOST RETAIDEO IN THE HISTORY OF SCIENCE

Fantastic video!
