Principles of General, Organic, and Biological Chemistry [EXP-50614]

A sample of exhaled air from the lungs contains four gases with the following partial pressures: $N_{2}$ (563 mm Hg), $O_{2}$ (118 mm Hg), $CO_{2}$ (30. mm Hg), and $H_{2}O$ (50. mm Hg). What is the total pressure of the sample?
Analysis
Using Dalton’s law, the total pressure is the sum of the partial pressures.
