Chapter 11.6, Problem 11.11WE

Interpretation Introduction

Interpretation:

The excluded volume of two molecules, the excluded volume per mole for the gas and the excluded volume per mole with the volume actually occupied by a mole of the molecules has to be calculated.

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 $\frac{\text{4}}{\text{3}}{\text{πr}}^{\text{3}}\text{;}{\text{N}}_{\text{A}}\text{=6}\text{.022}\text{×}{\text{10}}^{\text{23}}$

To determine: The Excluded volume defined by two molecules
