1.12 Dalton's Law of Partial Pressures

907 kPa

A 5.0 L vessel holds 3.0 mol N2, 2.0 mol F2, and 1.0 mol H2 at 273 K. What is the partial pressure of fluorine?

558 kPa

A mixture of Ar, He, and O2 has a total pressure of 1,015 kPa, and partial pressures of argon and helium of 152 kPa and 305 kPa, respectively. What is the partial pressure of oxygen in this mixture?

2.04 × 10^4 kPa

A tank of gas has partial pressures of nitrogen and oxygen equal to 1.61 × 10^4 kPa and 4.34 × 10^3 kPa, respectively. What is the total pressure of the tank? Remember that (1.0 × 10^5) + (1.0 × 10^5) = 2.0 × 10^5.

146.4 kPa

At 298 K, you collect 0.5 L of oxygen over water that has a total pressure of 150 kPa. What is the partial pressure of oxygen? (The partial pressure of water vapor at 298 K is 3.6 kPa.)

105 kPa

At a depth of 40 m, the water pressure is 500 kPa. A diver breathing air (78% N2, 21% O2) at this depth would have what partial pressure of oxygen in his lungs?
