Chapter 10, Problem 33QP

Interpretation Introduction

Interpretation:

The reason for the fact that the density of gas is lower than liquids or solids, under atmospheric conditions is to be explained. The units for the density of gases are to be determined.

Concept introduction:

From the ideal gas equation, the relationship between density and molar mass can be represented as:

$d=\frac{PM}{RT}$

Here, M represents the molar mass of the gas, $P$ is the pressure, $R$ is the gas constant and $T$ is the temperature.

Density is defined as the ratio of mass to volume.
