Chapter 12, Problem 96CE

Interpretation Introduction

Interpretation:

Density of air at $17°\text{C}$ and $450\text{ torr}$ has to be determined.

Concept Introduction:

Ideal gas law represents equation to relate volume and pressure with temperature of ideal gas. Expression for ideal gas equation is as follows:

  $PV=nRT$        (1)

Here,

$P$ is pressure of the gas.

$V$ is volume of gas.

$n$ denotes moles of gas.

$R$ is gas constant.

$T$ is temperature of gas.

Density of gas represents mass of gas present in unit volume. Expression of density is as follows:

  $d\left(\text{g/L}\right)=\frac{\text{mass}\left(\text{g}\right)}{\text{volume}\left(\text{L}\right)}$

Here, $d$ is density of gas.
