Question Analysis
This question involves the mole fraction version of Dalton’s Law of Partial Pressures. The main focus is on calculating partial pressure using the ratio of moles of a gas to the total moles of the mixture.

Key Concept Explanation
The mole fraction ( ) of a gas is the ratio of the moles of the gas ( ) to the total moles ( ) of the mixture:

The partial pressure of a gas can also be calculated as:

This formula is valid for ideal gas mixtures at constant temperature and volume.

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