Chapter 11, Problem 75E

Interpretation Introduction

Interpretation:

The partial pressure of helium in mixture is to be determined.

Concept introduction:

According to Dalton law of partial pressure, the total pressure of a mixture of gas is the sum of partial pressure of itsgaseous components.

Mathematically, it will be:

$P_{\text{tot}}=P_{\text{a}}+P_{\text{b}}+P_{\text{c}}+\mathrm{...}$

Here, $P_{\text{tot}}$ is the total pressure and $P_{\text{a}},P_{\text{b}},P_{\text{c}},\mathrm{...}$ are the partial pressures of the

components.
