WebIn an effusion experiment at 75C, 12.1 mL of this compound escapes through the pinhole in 10.0 minutes. Under the same conditions, 11.9 mL of carbon dioxide effuses in 5.0 minutes. Using this information, determine the chemical formula of the unknown compound. Solution: According to Grahams law of diffusion, rate of effusion of a gas is ... WebFeb 26, 2016 · Explanation: Graham's Law of Effusion tells you that the rate of effusion of a gas is inversely proportional to the square root of the mass of the particles of gas. This can be written as rate of effusion ∝ a 1 √molar mass Essentially, the rate of effusion of a gas will depend on how massive its molecules are.
