About Molar Mass of Gas
The molar mass of a gas can be determined using various methods based on gas laws and physical properties. This is essential for identifying unknown gases.
Ideal Gas Law:
M = (mRT) / (PV)
From Density:
M = (dRT) / P
Graham's Law:
M₁/M₂ = (r₂/r₁)²
Where R = 0.0821 L·atm/(mol·K), d = density, r = effusion rate, and M = molar mass.
