Chapter 3, Problem 3B.19E

(a)

Interpretation Introduction

Interpretation:

Molar volume of an ideal gas at $1\text{atm}$ and at $500°\text{C}$ has to be determined.

Concept Introduction:

The mathematical relation between volume and amount at constant pressure as per the Avogadro’s law is as follows:

  $V=\left(\text{constant}\right)\times n$

Here,

$V$ denotes the volume.

$n$ denotes the number of moles.

Or it can also be expressed as follows:

  $\frac{V_1}{n_1}=\frac{V_2}{n_2}$

Here,

$V_1$ is the initial pressure.

$V_1$ is the final pressure.

$n_1$ is the initial temperature.

$n_1$ is the final temperature.
