Dalton's Law of Partial Pressures can be used to simplify gas stoichiometry problems. As a derivative of the ideal gas law, Dalton's Law assumes that gas particles are featureless little billiard balls, bouncing off each other and the walls of their container. Because of the assumption of ideality, 20 moles of helium, a mixture of 16 moles of nitrogen and 4 moles of oxygen, or a mixture of 10 moles of water vapor, 8 moles of carbon dioxide, and 2...
