5. A sample of exhaled air contains four gases with the following partial pressures: N2 (563 mm Hg), O2 (118 mm Hg), CO2 (30 mm Hg), and H2O (50 mm Hg). What is the total pressure of the sample? According to Dalton's Law, the total pressure is the sum of all of the individual gas pressures. That is, just add them up.
6. What volume of ammonia is produced when 0.500 mole of nitrogen reacts completely in the following equation? 2NH3(g) → N2(g) + 3 H2(g)

Name Dalton's Law of Partial Pressures - Many gas samples are a mixture of gases. For example, air is a mixture of gases. The gases dissolved in blood make up a mixture as well. In a gas mixture, each gas exerts its partial pressure (the specific pressure contribution of the gas to the total pressure of the gas mixture). Dalton's law states that the total pressure of a gas mixture (Pita) is the sum of the partial pressures of the...
