Chapter 1, Problem 1C.7P

(a)

Interpretation Introduction

Interpretation: The molar volume of water vapour has to be calculated.

Concept introduction: The volume occupied by the gas per mole is defined as the molar volume.  It is designated by $V_{\text{m}}$.  The formula used for molar volume is,

    $\text{Molar}\text{Volume},V_{\text{m}}=\frac{\text{Molar}\text{mass}}{\text{Density}}$

(b)

Interpretation Introduction

Interpretation: The compressibility factor from the given data has to be calculated.

Concept introduction: The compression factor is defined as the ratio of molar volume of a gas to the molar volume of a perfect gas.  This is represented by the formula given below as,

  $Z=\frac{V_{\text{m}}}{V_{\text{m}}^{\text{°}}}$

(c)

Interpretation Introduction

Interpretation: The compressibility factor from the virial expansion of van der Waals equation has to be calculated.

Concept introduction: The compression factor is defined as the ratio of molar volume of a gas to the molar volume of a perfect gas.  This is represented by the formula given below as,

  $Z=\frac{V_{\text{m}}}{V_{\text{m}}^{\text{°}}}$
