Question Analysis
This question involves converting gas masses to moles, calculating total moles for a three-component mixture, and applying the mole fraction form of Dalton’s Law. The main focus is on integrating stoichiometric mass-mole conversions with partial pressure calculations for a multi-gas system.

Key Concept Explanation
For mass-based gas mixture problems, first convert mass to moles using ( ).
Then calculate the mole fraction of the target gas: .
The partial pressure is found via . This method is valid for non-reacting ideal gas mixtures.

Step-by-Step Solution
1. Calculate moles of each gas:
