Chapter 11, Problem 80E

Interpretation Introduction

Interpretation:

The total pressure of the gas sample is to be determined.

Concept introduction:

According to Dalton law of partial pressure, the total pressure of the gas is the partial pressure of its component gases. 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.

The formula used to calculate the partial pressure of component is: $\begin{array}{l}\text{Partial Pressure of component}\begin{array}{cc}=& \end{array}\begin{array}{ccc}\begin{array}{l}\text{Fractional composition}\\ \text{of component}\end{array}& \times & \text{Total Pressure }\end{array}\\ \end{array}$
