Chapter 5, Problem 67E

Interpretation Introduction

Interpretation:Ratio of final volume to initial volume for reaction of formation of ${\text{SO}}_{\text{3}}$ should to be calculated.

Concept introduction:Avogadro’s gaseous lawsuggests volume is directly related to moles of ideal gas, provided temperature and pressure remain constant.

Mathematically, the relation that holds true between volume and moles that holds true is as follows:

  $\begin{array}{c}V\propto n\\ \frac{V}{n}\text{= constant}\end{array}$

The consequence of Avogadro’s law is that it enables equal volume to contain equal moles and hence coefficients that denote moles also denote the volume of each reactant.
