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.
Diffusion is the movement of particles, often times a gas, from a region of a higher concentration to a lower concentration region.
Diffusion is used in fields such as physics, chemistry, biology, and more.
