Chapter 20, Problem 12QAP

Interpretation Introduction

Interpretation:

The volume of sulfur dioxide produced under the given conditions should be calculated when one boxcar load of chalcopyrite ore is roasted.

Concept introduction:

The moles of any compound or element can be calculated by given formula:

  $n=\frac{m}{M}$

Where, n is number of moles, m is given mass, and M is molar mass of the element/compound.

To obtain the volume of gases, the ideal gas equation is used as

  $\begin{array}{l}PV=nRT.\\ \text{Where}\text{. P is pressure, V is volume, n is number of moles, R is gas constant and T is temperature}\text{.}\end{array}$ or $\text{V=}\frac{nRT}{P}$

The mass of any compound can be obtained as

  $Mass=Volume\times Density$

The conversion factor will be used for the volumes in liter and cubic centimeter.
