Chapter 5, Problem 5.43P

Interpretation Introduction

Interpretation:

The partial pressure of gas A in a mixture and mole fraction of gas A is to be compared.

Concept introduction:

The mole fraction is defined as the ratio of the number of moles of solute to the total number of moles in the mixture. It is represented by $X$.

The formula to calculate the mole fraction is as follows:

  $\text{Mole}\text{fraction}\left(X\right)=\frac{\text{amount}\left(\text{mol}\right)\text{of}\text{component 1}}{\left(\begin{array}{l}\text{amount}\left(\text{mol}\right)\text{of}\text{component 1}+\\ \text{amount}\left(\text{mol}\right)\text{of}\text{component 2}\end{array}\right)}$        (1)

In a mixture of gases, the pressure exerted by individual component is known as partial pressure. The sum of the partial pressure of components is equal to the total pressure.
