Molar mass of gas

`M = (m*R*T)/(P*V)`

Calculator of molar mass of gas.

This calculator calculates molar mass of gas according to the following formula,

`M = (m*R*T)/(P*V)`

M: molar mass of gas in kg/mol
m: mass of gas in kg
P: gas pressure in Pa
V: volume of gas in cubic meter
T: gas temperature in Kelvin
R: Ideal Gas Constant, `R \approx 8.314463\ J*mol^{-1}*K^{-1}`

This formula assumes that the Ideal Gas Law applies that is, the interactions between molecules of the gas are negligible. This condition excludes therefore high pressures and temperatures.
