Chapter 6, Problem 65E

Interpretation Introduction

Interpretation:

The final pressure of the mixture having 4.0 L oxygen gas, 2.0 L nitrogen gas should be calculated.

Concept introduction:

The Boyle’s law of ideal gas states that at constant temperature and constant number of moles, the pressure of ideal gas is inversely proportion to the volume of gas. For two different conditions of pressure and volume, it can be written as:

${\text{P}}_{\text{1}}{\text{V}}_{\text{1}}{\text{ = P}}_{\text{2}}{\text{V}}_{\text{2}}$

If there will be a mixture of two or more gases then the final pressure and volume of mixture can be calculated as:

${\text{P}}_{\text{1}}{\text{V}}_{\text{1}}{\text{ + P}}_{\text{2}}{\text{V}}_{\text{2}}{\text{+ P}}_{\text{3}}{\text{V}}_{\text{3}}\text{+ … = PV}$
