Question Analysis
This question tests the student's understanding of Dalton's Law of Partial Pressures, specifically the concept that the total pressure of a gas mixture is the sum of the partial pressures of its components.

Key Concept Explanation
Dalton's Law of Partial Pressures states that the total pressure of a gas mixture is the sum of the partial pressures of each individual gas in the mixture.

Step-by-step Solution
1. Identify the partial pressures of the gases: 150 kPa, 200 kPa, and 250 kPa.
2. Add the partial pressures together: .
3. Perform the addition:
