The effusion rate of a gas is inversely proportional to the square root of its molecular mass. ... With Graham's Law, you can find the effusion rates for two gases or the molecular mass of a gas. This ratio of effusion rates follows the pattern that the gas with the lesser molecular mass has a greater rate of effusion.

In 1846 Thomas Graham discovered that the effusion rate of a gas is inversely proportional to the square root or its molar mass. If the rate of effusion or two gases, at the same temperature and pressure, are r1 and r2, and their respective molar masses are M1 and M2 Graham's law states:

This equation is used to calculate the rate of effusion of a second gas from data about the rate of effusion of the first gas and the masses of both gases. It is important to consider whther a gas exists as a diatomic in this equation.
