Chapter 9, Problem 82AP

Interpretation Introduction

Interpretation:

The mass of ${\text{SO}}_{\text{3}}$ formed should be calculated.

Concept Introduction:

The commercial production of sulphuric acid, ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ involves the following step in which sulphur dioxide, ${\text{SO}}_{\text{2}}$ is converted into sulphur trioxide, ${\text{SO}}_3$ as follows:

${\text{2SO}}_{\text{2}}\left(\text{g}\right)+{\text{O}}_{\text{2}}\left(\text{g}\right)\to {\text{2SO}}_{\text{3}}\left(\text{g}\right)$

The mass of ${\text{SO}}_3$ can be calculated by calculating the number of moles of ${\text{SO}}_3$ formed in the reaction.
