Graham's Law of Effusion Quiz

What is the relative rate of diffusion of NO₂ ?

Carbon dioxide molecules have an average speed of 25.0 m/s at a given temperature and pressure. What is the average speed of carbon monoxide molecules at the same conditions?

An unknown gas diffuses 0.25 times as fast as helium. What is its molar mass?

Determine the rate of effusion of the densest gas known, UF_6, to that of the lightest gas, H₂.

A sample of neon gas effuses from a container at a rate of 2.18 x 10^-2 moles per minute. In a separate trial, an unknown gas effuses from the same container at a rate of 8.66 x 10^-3 moles per minute. What is the molar mass of the unknown gas?

If a molecule of neon gas travels at an average speed of 400 m/s at a given temperature, find the average speed of a molecule of butane gas, C₄H₁₀, at the same temperature?

Methane (CH₄) effuses at a rate of 2.45 mol/s. What will be the effusion rate of argon (Ar) under the same conditions?
