Chapter 5, Problem 87E

Interpretation Introduction

Interpretation: The total pressure, the partial pressures of each gas in the given figure is needed to be determined when the stop-cocks are opened.

Concept introduction:

• Partial pressure of a gas in a mixture of gases is the pressure of that gas when it alone.

• Total pressure of a mixture of gases is the sum of individual partial pressures of constituted gases.

• According to Boyle’s law of gas molecules,

  If the volume of gases in a container is increased then the pressure will decrease at constant temperature and number of moles.

  Equation for Boyle’s law is,

  ${\text{P}}_{\text{initial}}{\text{V}}_{\text{initial}}\text{=}{\text{P}}_{\text{final}}{\text{V}}_{\text{final}}$
