awesome great!

[JAYtheMAN2121]

DAAAAAAAAAAAAAANG.... if you were an enzyme, you could unzip my jeans any day

[muaazchoudhary]

do u always multiply by two when u get a decimal number?

[1217sable]

@muaazchoudhary U would multiply whatever it takes to get a whole number

[Austin11Weber]

@muaazchoudhary by whatever number till you get a whole number i'm pretty sure

[muaazchoudhary]

@Austin11Weber thanks

[jonathan3979701]

ty although u might wanna talk a bit slower but ty it did help

[CaptainBroha]

@jonathan3979701

All the chem prof's I have ever had talk this fast haha. It comes with the major I guess.

[waishoforlife]

why did we multiplay NO1.5 by 2??

[kerrie337]

@waishoforlife  because empirical formula shouldnt have decimals, so the way to get 1.5 to a whole number is to times it by 2 this gives you 3.

same goes for if you had NO 1.25 you would multiply it by 4 ( 0.25 * 4 = 1) NO would then be 5

[likeastarrr2]

thank you sooo much, got some homework about this and didn't even do it in the lesson and everyone else in the seemed to know what they were doing,

thanks again!!!!

[jennellalor]

thanks mam good Explaining

[tayyabhassanzahidkmk]

Aslamo alikum. u r outstanding teacher of chemistry subject. ur videos will become charming if u reduce ur speaking speed.

[getdown1983]

:The relativ atom masses are to handel (addit) with (g/mol=x*10^-36) for the exactly molecularmass, divide it by the number of atoms and verb they paralell to the exactly ratio you want. You can to addit the sames atoms before do the paralell verbs.

It is a kind of magic sure.

Amazon.de sell an periodensystem with relative atommasses and more (study knowledge).

I like the texas instrument calculators (not the cheapest.)

[GARYmetallica]

Thank you very much, really helpful!

[label1994]

I understand methane being CH4. What molecule has a formula C6H24?! Or C18H72? Alkanes are the most saturated hydrocarbons and their formula is CnH2n+2, For C=6, the greatest number of hydrogens a hydrocarbon molecule can contain is 2(6)+2 = 14.

This does a nice job of explaining the concept, I just wish you would have used (possible) real compounds to do it.

[TheOverload01]

@label1994 you're right :D

[35413541ful]

I relly liked the way you explained. YOu make it very easy, just one thing, can you talk a little bit slower please! Your videos are great thou!
