Chapter 9, Problem 9.64SP

(a)

Interpretation Introduction

Interpretation:

The density of the ${\text{CH}}_{\text{4}}$ gas has to be calculated.

Concept Introduction:

Density = an amount of substance per unit volume is known as density.

$\begin{array}{l}\text{ ρ = }\frac{\text{M}}{\text{V}}\\ \text{Where,}\\ \text{ρ=density}\\ \text{M=mass}\\ \text{V=Volume}\end{array}$

(b)

Interpretation Introduction

Interpretation:

The density of the ${\text{CO}}_{\text{2}}$ gas has to be calculated.

Concept Introduction:

Density = an amount of substance per unit volume is known as density.

$\begin{array}{l}\text{ ρ = }\frac{\text{M}}{\text{V}}\\ \text{Where,}\\ \text{ρ=density}\\ \text{M=mass}\\ \text{V=Volume}\end{array}$

(c)

Interpretation Introduction

Interpretation:

The density of the ${\text{O}}_{\text{2}}$ gas has to be calculated.

Concept Introduction:

Density = an amount of substance per unit volume is known as density.

$\begin{array}{l}\text{ ρ = }\frac{\text{M}}{\text{V}}\\ \text{Where,}\\ \text{ρ=density}\\ \text{M=mass}\\ \text{V=Volume}\end{array}$
