Chapter 5.5, Problem B5.3P

Interpretation Introduction

Interpretation:

The volume percent and partial pressure of argon in a sample are to be calculated.

Concept introduction:

According to the Dalton law, the total pressure exerted by a mixture of non-reacting gases is equal to the summation of the partial pressure of individual gases.

The Dalton law is repressed as follows:

  $P_{gas}=X_{\text{gas}}\cdot P_{\text{total}}$

Here,

$P_{gas}$ is the partial pressure of the gas.

$P_{\text{total}}$ is the total pressure of the mixture.

$X_{\text{gas}}$ is the mole fraction of gas.
