Professor Dave Explains
Practice Problem: Graham's Law of Effusion
We know that molecules will travel at an average velocity that is inversely proportional to their molar mass. This means that lighter gases travel faster. We can relate the rates of effusion for two gases using Graham's law, and we can...

Khan Academy: Gas Exchange: Graham's Law of Diffusion
Find out whether oxygen or carbon dioxide has a higher rate of diffusion in this video lecture. Lecture discusses the euqation to find out how to relate diffusion of gases to their molar masses. [8:56]
