Chapter 10, Problem 109AP

Interpretation Introduction

Interpretation:

The partial pressure of the given mixtures of gases should be measured by physical or chemical means is to be described.

Concept introduction:

The mole fraction of an individual gas for the combination of gases is the ratio of the moles of the individual gas with the total number of moles.

${\chi }_i=\frac{n_i}{n_{\text{total}}}$

Here, ${\chi }_i$ is the mole fraction, $n_i$ is the number of moles of the individual gas, and $n_{\text{total}}$ is the total number of moles.

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.

${\chi }_i=\frac{P_i}{P_{\text{total}}}$

Here, ${\chi }_i$ is the mole fraction, $P_i$ is the partial pressure of the individual gas, and $P_{\text{total}}$ is the total pressure.
