Question Analysis
This question evaluates the student's understanding of Dalton’s Law of Partial Pressures, specifically how to calculate the partial pressure of one component in a gas mixture when the total pressure and the partial pressures of other components are known.

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. The partial pressure of a specific gas can be found by subtracting the partial pressures of the other gases from the total pressure.

Step-by-step Solution
1. Identify the given values: Total pressure , partial pressure of nitrogen , and partial pressure of oxygen .
2. Use the formula for the total pressure:
