Question Analysis
This question involves calculating the partial pressure of a noble gas in a three-component mole-based mixture using Dalton’s Law. The main focus is on mole fraction calculation for a mixture of inert gases.

Key Concept Explanation
Noble gases are non-reacting, so Dalton’s Law applies directly. The partial pressure formula for mole-based mixtures is:

where is the sum of moles of all gases in the mixture.

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

2. Calculate the mole fraction of :
