# Molar Mass of Gas

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Molar mass is the mass in atomic mass units, of one mole of a substance.

### Molar Mass of Gas formula

$$\large{ M = v \:\cdot\: 0.0821 \left( \frac {G}{T} \right) p }$$

Where:

$$\large{ M }$$ = molar mass of gas

$$\large{ G }$$ = mass of gas

$$\large{ p }$$ = pressure

$$\large{ T }$$ = temperature

$$\large{ v }$$ = volume
