Graham's law of diffusion experiment

Web1) We can use Grahams' law to determine the molar mass of an unknown gas by comparing its rate of diffusion to the rate of diffusion of a gas with a known molar mass. In this experiment, we will measure the relative … WebIn 1829 Graham published the first of his papers relating specifically to the subject of gaseous diffusion ( Graham, 1829a ). He allowed hydrogen (or oxygen) to escape through a small hole in a plate of platinum and found that hydrogen molecules moved out four times faster than those of oxygen.
