Interpretation Introduction

Interpretation:

The volume(in ${\text{cm}}^3$)of ore removed each year and the mass ($\text{kg}$) of the ${\text{SO}}_2$ produced by roasting is to be calculated.

Concept introduction:

Density of an object is the ratio of the mass to the volume of that object.

The formula of density is expressed as follows:

$\text{Density}=\frac{\text{mass}}{\text{Volume}}$

The number of moles of a substance is the ratio of the mass of the substance to its molar mass.
