Question Analysis
This question assesses the student's understanding of Dalton’s Law of Partial Pressures, specifically how to calculate the partial pressure of other gases in a mixture given the total pressure and the partial pressure of one component.
Key Concept Explanation
According to Dalton’s Law of Partial Pressures, the total pressure of a gas mixture is the sum of the partial pressures of each component gas.
The partial pressure of a component gas is the pressure it would exert if it alone occupied the entire volume of the mixture at the same temperature.
Step-by-step Solution
1. Identify the total pressure of the gas mixture: .
2. Identify the partial pressure of nitrogen: .
3. Use Dalton’s Law to find the partial pressure of the other gases:
