Question

Graham's law of diffusion give its usefulness in coal mines brainly.In

Answer 1

Graham's law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight. ... Therefore the rate of diffusion of different gases is inversely proportional to the square root of their mass densities.
