Question Analysis
This question involves the mole fraction application of Dalton’s Law to a three-component gas mixture. The main focus is on calculating partial pressures for all components, requiring accurate total mole and mole fraction calculations.

Key Concept Explanation
The mole fraction formula for partial pressure is:

where is the sum of moles of all gases in the mixture. For a multi-component mixture, the sum of all partial pressures must equal the total pressure (a good way to check your answer).

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

2. Calculate the mole fraction and partial pressure for each gas:
