Chapter 5, Problem 5.56QP

Interpretation Introduction

Interpretation:

The total pressure and mole fraction has to be calculated.

Concept Introduction:

• The pressure exerted by an individual gas in a mixture is known as its partial pressure.
• Assuming we have a mixture of ideal gases, we can use the ideal gas law to solve problems involving gases in a mixture.
• Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases:
• A mole fraction is the unit less proportion of the number of moles of a mixture constituent and the total number of moles in the mixture.
• ${\text{χ}}_{\text{i}}\text{=}\frac{{\text{P}}_{\text{i}}}{{\text{P}}_{\text{total}}}$

${\text{P}}_{\text{i}}={\text{χ}}_{\text{i}}\times {\text{P}}_{\text{total}}$
