Molar Mass of Gas
Molar mass is the mass in atomic mass units, of one mole of a substance.
Molar Mass of Gas formula
\(\large{ M = v \:\cdot\: 0.0821 \left( \frac {G}{T} \right) p }\)
Where:
\(\large{ M }\) = molar mass of gas
\(\large{ G }\) = mass of gas
\(\large{ p }\) = pressure
\(\large{ T }\) = temperature
\(\large{ v }\) = volume
