Question Analysis
This question involves calculating the partial pressure of a target gas in a three-component mole-based mixture using Dalton’s Law. The main focus is on determining mole fraction and applying it to find partial pressure.

Key Concept Explanation
For mole-based gas mixtures, Dalton’s Law uses the relationship:

where mole fraction , = moles of target gas, = total moles of the mixture, and = total pressure of the system. This applies to non-reacting ideal gas mixtures.

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