Interpretation:
The partial pressures of the gasespresent in the given mixture of gases are to be calculated.
Concept introduction:
The mole fraction of an individual gas for the combination of gases is the ratio of the moles of the individual gas to the total number of moles of the mixture.
Here,
Also, the mole fraction of an individual gas for the combination of gases can be calculated from the ratio of the partial pressure of the individual gas with the total pressure of the combination.
Here,

Answer to Problem 66QP
Solution: The partial pressure for
Explanation of Solution
Given information:
Number of moles of
Number of moles of
Number of moles of
Total pressure
From Dalton’s law for the combination of gases, the total number of moles can be calculated as
