Chapter 6.8, Problem 6.21P

Interpretation Introduction

Interpretation:

The partial pressures of each gas in the mixture have to be given.

Concept Introduction:

The partial pressure of the gas can be obtained by multiplying the total pressure of the mixture with the percent of the gases present in the mixture.

Dalton’s Law:

The total pressure of a gas mixture is the sum of the partial pressures of its component gases.

  ${\text{P}}_{\text{total}}{\text{=P}}_{\text{a}}{\text{+}}_{\text{b}}\text{+}\mathrm{...}$

Where ${\text{P}}_{\text{a,}}{\text{P}}_{\text{b}}$ is the partial pressure of the gases in the mixture.

The partial pressure of any gas in a gaseous mixture is defined as the pressure that the gas would exert if the gas presents in the same container and at the same pressure.
