Chapter 3, Problem 3B.36E

(a)

Interpretation Introduction

Interpretation:

Density of ${\text{NH}}_3$ vapor at $1\text{atm}$ and $298\text{K}$ has to be determined.

Concept Introduction:

Expression that relates density, molar mass, pressure, temperature, and gas constant for an ideal gas is as follows:

  $d=\frac{MP}{RT}$

Here,

$d$ is density of object.

$M$ is molar mass.

$P$ is pressure.

$R$ is gas constant.

$T$ is the temperature.

(b)

Interpretation Introduction

Interpretation:

Density of ${\text{NH}}_3$ vapor at $0.865\text{atm}$ and $32\text{°C}$ has to be determined.

Concept Introduction:

Refer to part (a).
