Chapter 13, Problem 13.131P

(a)

Interpretation Introduction

Interpretation:

The scene that represents the smallest mole fraction of nitrogen is to be identified.

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:

$\text{Mole}\text{fraction}\left(X\right)=\frac{\text{amount}\left(\text{mol}\right)\text{of}\text{component 1}}{\begin{array}{l}\text{amount}\left(\text{mol}\right)\text{of}\text{component 1}+\\ \text{amount}\left(\text{mol}\right)\text{of}\text{component 2}+\\ \text{amount}\left(\text{mol}\right)\text{of}\text{component 3}\end{array}}$ (1)
