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 binary mixture using its mole fraction and the given total pressure.

Key Concept Explanation
Dalton’s Law of Partial Pressures can be expressed using mole fraction ( ), which is the ratio of the moles of a single gas to the total moles of the mixture. The formulas are:


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

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