Helium effusion rate

Web12 feb. 2024 · For a gas, the rate at which diffusion occurs is proportional to the square root of the density of the gas. The density of a gas is equal to the mass of the gas divided by the volume of the gas. If the volume is held constant one gas is compared with another with another, R 2 R 1 = M 1 M 2. where R is the rate of diffusion in mol/s and M is the ...
