Answer 2

So I want to use the equation PV = mRT not PV = nRT

m is the mass

Answer 3

Look at this table, page 5

Answer 4

yeah let me see

Answer 5

page 4

Answer 6

nice table

Answer 7

That table will break my neck if I stare at it for too long.

Answer 8

I am trying to solve for Volume I can't get the units straigtened out

Answer 9

For my exams she is giving us this table and I won't be able to solve for n when I don't have m or M

Answer 10

so then, this is more algebra than unit coversion...

Answer 11

well n = m/M m = mass of gas M = molecular weight of gas.

Answer 12

in the able R = R/M , the R on top should have a line above it.

Answer 13

ratio of gas constant to molecular weight

Answer 14

\[n = \frac{ m }{ M } = \frac{ grams }{ \frac{ grams }{ mole } } = moles\]

Answer 15

what units are you supposed to use for R maybe if we know that we can figure this out

\[pV = mRT \]

Answer 16

yeah, because M is the molecular weight in grams/mole

Answer 17

I am not going to use PV = mRT I want to use PV = nRT so n = m/M so how would I find m ? @confluxepic

Answer 18

I am not given a mass soooo....
