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

Key Concept Explanation
Dalton’s Law of Partial Pressures uses mole fraction ( ) to relate the amount of a gas to its partial pressure. The core formulas are:


where = moles of the target gas, = total moles of the mixture, = partial pressure of the target gas, and = total pressure of the mixture. This is only valid for non-reacting ideal gases.

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