Chapter 11, Problem 76E

Interpretation Introduction

Interpretation:

The composition of the mixture is to be determined.

Concept introduction:

Dalton’s law of partial pressure states that the sum of the partial pressure of gaseous components in a mixture is equal to the total pressure.

The equation for Dalton’s Law is:

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

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 various components.

The partial pressure of a component is related with total pressure with the equation as:

$\text{Partial Pressure of component}=\text{Fractional composition of component}\times \text{Total Pressure}$
