Question Analysis
This question involves converting the mass of gases to moles and then applying the mole fraction version of Dalton’s Law. The main focus is on integrating stoichiometric mass-mole conversion with partial pressure calculation.

Key Concept Explanation
To use Dalton’s Law with mass values, first convert mass to moles ( , where = mass, = molar mass). Then calculate mole fraction ( ) and partial pressure ( ). This applies to non-reacting ideal gas mixtures.

Step-by-Step Solution
1. Calculate moles of and :
