Calculating Moles from Grams (Mass to Moles)

[ThatSephKid]

i love you

[RuMpFoRLiFe]

I may as well ask this stupid question that i don't understand seeing as if i ask my teacher again I would suspect his going to punch the hell out of me but why do u find out Moles? I DONT UNDERSTAND, is the amount of moles used to find the atoms of something? yes its a stupid question but i just don't understand.

What are the number of moles in each compound?

1.4 x 10^13 molecules of H2



, The following quantities of trace gases were found in a 1 mL sample of air

big thank you from saudi arabia ,,

[Xocuter]

Thank you so much! That made everything so simple for me. :)

[LuzLuz15]

can you please make a video of how we calculate the number of Moles in Gases and Solutions?

[eminemandshanedawson]

you saved my ass

BIG THANKS!!

very easy to understand

[eminemandshanedawson]

THANK YOUUUU SOOOO MUCHHHHHHH!!!!!

[basilishere]

Very easy to understand and precise, thank you much

The relativ atom mass is to handel with (g/mol=x*10^-36) for the exactly molecularmass and so the exactly ratio.

Example: The molecular mass divide by the number of atoms and then to ratiomasses you want.

thank you, you explained very simple and easy to understand.

hi your videos been very helpful!

but im a little bit consfused, how do u calculate if a question is something like this: Calculate the number of grams of each substance needed to make

Example:

a)1 litre of 1 M NaCl

b)100 ml of 2 M acetic acid

thank you

[NeonNeutron]

it all makes sense now. Thank You for posting!!!!
