mole number 1

[tarek12]

hello
i would like to know how we can calculate tne mole number of a real gaz
since we have as data the molecular weight,molar density ; masse density the temprerature and the pressure
Best regards

PV = znRT, therefore n = PV/zRT.

Good Luck,
Latexman

Latexman
but we dont have the volume

tarek12,

Then you have to settle for molar density. No choice, until one knows the volume of the problem.

n/V = P/zRT

Good Luck,
Latexman

Latexman
many thx

Hi,
You did not ask for Z calculation.
You may be interested in the spreadsheet attached.
Good luck
