# Molar Mass of Gas

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

## Molar Mass of Gas formula

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

### Where:

\(\large{ M }\) = molar mass of gas

\(\large{ G }\) = mass of gas

\(\large{ p }\) = pressure

\(\large{ T }\) = temperature

\(\large{ v }\) = volume
