1. One-third of a gaseous mixture is nitrogen and 2/3 of the gas is helium. The total pressure in the container is 3 atmospheres. What is the partial pressure of the nitrogen?

2. A sealed vessel contains 50% oxygen, 10% carbon dioxide, and 40% nitrogen gas. The total pressure of the gas mixture is 5 atmospheres. What is the partial pressure of the carbon dioxide?
