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.
Jesseca Alba 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.

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.
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...........
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!
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.
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!!!
Wow, that's very kind, Jeannelle. :) But for now, the best way to repay me is to keep sharing my videos with classmates, friends, and family. All the best!
Sounds like you have a periodic table with limited significant figures. You'll get roughly the same answer, but your significant figures (precision) will be slightly off.

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
+alien “sam the best player” bro Hello Sameer, unfortunately I don't have time to help students individually which is why I've recorded these videos so that I can help thousands at once! But I hope you continue to check back. :)

Jesseca Alba Fantastic news, Jesseca! Congrats! That's very encouraging. :)

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!
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

Im here because my teacher forced me to watch you video, but I found your voice very soothing, so thank you.
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!!!
You're very welcome! Glad it helped. :)
I wish more people in my class would watch these! They are so helpful!
Thanks so much! I missed a few days of chemistry class as I was sick and this got me back on track!
Awesome! Glad you kicked butt on the second test! Way to go!
This is so clear , so grateful you put this on to help. I hope I get a good grade on my test!
Best video on explaining the mole and molar mass!!!
Thanks for the kudos, Amanda! So glad you found this video helpful. Be sure to subscribe to be notified when new lessons are posted!
How do i give you guys money.... i love what you have done for my understanding in this!!!!!
Wow, that's very kind, Jeannelle. :) But for now, the best way to repay me is to keep sharing my videos with classmates, friends, and family. All the best!
Will do :)
Simple , sweet and crisp . Love it
Glad to hear it! Be sure to check out the other videos in our series on The Mole. :)
you saved my chemistry mark! i got 58 for last sem. i will get better mark after watching your videos. 😀
Good chemistry saves many a life. ;) Thanks for the encouragement!
Thank you so much, this is explaining everything so easy !!
Thanks so much, my teacher doesn't teach these lessons nearly as well as you do!
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.
Let's just keep this between us or my wife might get jealous. ;)
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!
you have done a great job ......(Thanks)
Fantastic video!
honestly, you saved my life.
what about for finding the number of atom of an element in a formula?
Thank you so much for this!!!
THANK YOU VERY MUCH U HELP ME ACE MY TEST!!!!
thanks so much... test in 2 days
You're very welcome! Best wishes on your test. :)
forgot to mention, thats more than enough to convice me to subsribe
I thank God for you because my teacher....... no comment
+Valencia Ing. Ha! You'd be surprised how many times I hear this... ;)
so helpful!!
thank you so much sir!!
You're very welcome! :)
thanks man
I don't really understand why the atomic mass of an atom is equal to its molar mass?
My periodic table is different
like i have the oxygen 16 and the Fe is 56
will it make a difference in the exam
Sounds like you have a periodic table with limited significant figures. You'll get roughly the same answer, but your significant figures (precision) will be slightly off.
In ur periodic table the masses are explained after the round off of no.
Fe, ( A-55.5) will become Fe( A-56)
Omg please be my teacherrr !!333
i need help . i don't understand Example 4 and so on
If you want to find the mass in grams it's grams on top and to find moles mass you put MOLES on the top
Use conversion factors. E.g 1 mole= __ g
This is awesome! Now I can make that blue meth I've been working on. ;)
I don't understand how you got 2.08 for number 5
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.
Hydrogen's Atomic Mass id 1.008. Save rounding oil the end. It gives you an answer that is more accurate!!!!
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,

I Want To Meet You!!!!
i love you
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.
