Answer 3

what about it?

Answer 4

so n = m/M right

Answer 5

n is moles

Answer 6

I am trying to solve for V and my gas is CO2 so how would I find the mass? It just me 44.01 g/mol * 1 mol / 6.022x10^23 ??

Answer 7

wait could you post your question so i can see what your trying to do.

Answer 8

It's a thermodynamics problem. I need to solve for V when I have T and P

Answer 9

All you have is T and P. No other variables

Answer 10

V = mRT/PM

Answer 11

we have M and R those are constants

Answer 12

And your gas is CO2? correct?

Answer 13

yes

Answer 14

Does it say the mass of CO2 you have or anything?

Answer 15

#2

Answer 16

oh so your given n aswell but not M

Answer 17

ignore that n

Answer 18

that is for something else.

Answer 19

That is for another equation. The n is not in mols

Answer 20

Yea i noticed it wasnt moles after reading more. is M representing mass?

Answer 21

M is g/mol

Answer 22

So m is grams?

Answer 23

yes

Answer 24

why can't I use 1mol = 6.022x10^23 ?

Answer 25

why would you want to convert to the number of atoms?

Answer 26

i'd use it to solve for grams

Answer 27

rather number of molecules*

Answer 28

V = mRT/PM

Answer 29

Look at page 5

Answer 30

originally i wanted to use PV = mRT but I don't know how to find m. The units for this class are weird...

Answer 31

you know what I think I just figured it out.

Answer 32

please share lol

Answer 33

wait holdon

Answer 34

@sweetburger nvm didn't find it
