Chapter 11.6, Problem 11PPC

Interpretation Introduction

Interpretation:

The given van der Waals factor is necessary or not has to be explained.

Concept introduction:

Use the formula for volume of a sphere to calculate the volume of a sphere of radius 2r. This is the excluded volume defined by two molecules.  Multiply the excluded volume per molecule by Avogadro’s number to determine excluded volume per mole.

The equation for volume of a sphere is $\frac{\text{4}}{\text{3}}{\text{πr}}^{\text{3}}\text{;}{\text{N}}_{\text{A}}\text{=6}\text{.022}\text{×}{\text{10}}^{\text{23}}$
