Question Analysis
This question involves the mole fraction application of Dalton’s Law of Partial Pressures. The main focus is on calculating the partial pressure of a specific gas in a three-component mixture using its mole fraction and the given total pressure in kilopascals.

Key Concept Explanation
Dalton’s Law of Partial Pressures can be applied with mole fraction ( ) to find the partial pressure of a gas in a mixture. The key formulas are:


where = moles of the target gas, = total moles of all gases in the mixture, = partial pressure of the target gas, and = total pressure of the mixture. This principle only holds for non-reacting ideal gases.

Step-by-Step Solution
1. Calculate the total moles of the gas mixture:
