Answer:

The molecular weight (molar mass) of any gas is the mass of one particle of that gas multiplied by Avogadro’s number (6.02 x 1023).

Knowing the molar mass of an element or compound can help us stoichiometrically balance a reaction equation.

The average molar mass of a mixture of gases is equal to the sum of the mole fractions of each gas (xi) multiplied by the molar mass (Mi) of that particular gas:
