Chapter 5, Problem 128E

Interpretation Introduction

Interpretation: The composition of mixture by volume is to be determined.

Concept Introduction:

➢ Ideal gas equation is as follows:

$PV=n\text{R}T$ …… (1)

Here, $P$ is pressure, $V$ is volume, $n$ is number of moles, $\text{R}$ is gas constant, and $T$ is temperature.

Rearrange above equation for $n$ as follows:

$n=\frac{PV}{\text{R}T}$

➢ The moles of gas is related to their molar mass as:

$n=\frac{\text{Mass}}{\text{Molar mass}}$

➢ Relation between density $\left(d\right)$ and mass is as follows:

$d=\frac{\text{mass}}{V}$

Here, $V$ is volume.
