Finding molar mass of gas
WebThe gas could well be CH 4, the only gas with this molar mass. Check Your Learning Hydrogen gas effuses through a porous container 8.97-times faster than an unknown gas. Estimate the molar mass of the unknown gas. Answer: … WebDec 9, 2024 · Graham's law states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molar mass. See this law in equation form below. r ∝ 1/ (M)½. or. r (M)½ = constant. In these equations, r = rate of diffusion or effusion and M = molar mass. Generally, this law is used to compare the difference in ...
