Chapter 1, Problem 1A.11BE

(i)

Interpretation Introduction

Interpretation: The mole fraction ${\text{H}}_{\text{2}}$ and ${\text{N}}_{\text{2}}$ in the given mixture at $273.15\text{K}$ has to be calculated.

Concept introduction: The partial pressure of any gas in a mixture of gases is calculated using the total pressure of the mixture and the mole fraction of the gas in the mixture.  This is represented by the formula given below as,

  $p_{\text{total}}=\frac{p_{\text{a}}}{x_{\text{a}}}$

The mole fraction of a component is calculated using the formula given below as,

    $x_{\text{a}}=\frac{n_{\text{a}}}{n_{\text{Total}}}$
