Enter the diffusion rate of a gas, its molar mass, and the molar mass of another gas to determine the diffusion rate of the second gas.

## Diffusion Rate Formula

The following formula is used to calculate the diffusion rate of a gas.

R2 = R1 / [Sqrt(M2/M1)]

- Where R2 is the diffusion rate of gas 2
- R1 is the diffusion rate of gas 1
- M2 is the molar mass of gas 2
- M1 is the molar mass of gas 1

To calculate a diffusion rate of a particular gas, divide the diffusion rate of the initial gas by the square root of the molar mass of gas 2 divide the molar mass of gas 1.

## Diffusion Rate Definition

A diffusion rate is defined as the rate of movement of particles from a region of higher concentrations to a lower concentration.

## Diffusion Rate Example

How to calculate diffusion rate?

**First, determine the diffusion rate of gas 1.**Measure the rate of diffusion of gas 1.

**Next, determine the molar masses.**Calculate the molar mass of both gas 1 and gas 2.

**Finally, calculate the diffusion rate.**Plug the values into the formula above to calculate the diffusion rate of the second gas.
