# How do you calculate the rate of diffusion of a gas?

Best answer

rate(gas A) × √molar mass(gas A) = rate(gas B) × √molar mass(gas B) This means that the relative rate of diffusion of two gases can be used to determine their relative molecular mass (or molar mass).

## What is the formula for rate of diffusion?

Graham's Law Formula Graham's law states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molar mass. See this law in equation form below. In these equations, r = rate of diffusion or effusion and M = molar mass.

## What is the formula of rate of diffusion?

The change in diffusing molecules over time is called the rate of diffusion. The diffusion rate of a gas is inverse to the square root of the volume (density). Hence, the rate of diffusion formula is: rate of diffusion ∝ 1/√density.
