How does Pressure affect molar mass?

  • #1
Will a higher pressure increase or decrease molar mass when using the ideal gas law, but solving for mm... (mm=mRT/PV)

I was thinking higher pressure would = decrease in molar mass, because of the gas laws and because p=1/v but im not sure if thats right

thanks!

Molar mass is not a function of pressure. PV=const, when you increase the pressure volume goes down and PV in denominator doesn't change.
