Chapter 5, Problem 45QAP

Interpretation Introduction

Interpretation:

The volume occupied by dry oxygen at a pressure 1.10 atm and a pressure of 27°C should be determined.

Concept introduction:

To solve the question, we have to use Dalton’s Law of partial pressure of gases according to which for a mixture of non-reacting gases, the sum of the partial pressures exerted by each individual gas in a mixture is equal to the total pressure of the mixture.

The expression for combined gas law is as below:

$\frac{P_1{V}_1}{n_1{T}_1}=\frac{P_2{V}_2}{n_2{T}_2}$

When P₁ and P₂ are pressure of gases, V₁ and V₂ are volume of gases, n₁ and n₂ are number of moles and T₁ and T₂ are temperatures at initial and final conditions respectively.
