• Diffusion Rate Calculator Effusion Formula. The following formula is used to calculate the rate of effusion. E ∝ 1 / Sqrt (M) Where E is the rate of effusion/effusion ratio M is the molar mass of the particles (g/mol) Effusion Definition. In most cases effusion is measured in mL/s however this equation results in a unitless number.

• ### Grahams Law of DiffusionRate of Effusion Solved

· Example 1 Calculate the molar mass of a given gas whose diffusion rate is 2.92 times the diffusion rate of NH₃. Answer We know that the diffusion rate is 2.92 times of ammonia hence we understand that the ratio of diffusion rates of the given gases should be 1/2.92. So r1/r2 = 1/2.92. Since we know that the molar mass of ammonia is 17.0307.
