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:
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
The mass of any compound can be obtained as
The conversion factor will be used for the volumes in liter and cubic centimeter.

Chalcopyrite (CuFeS2), is an important source of
copper. A typical chalcopyrite ore contains about
0.75% Cu. What volume of sulfur dioxide at 25ᵒC
and 1 atm pressure is produced when one boxcar
load ( 4 x 10^3 cu.ft) of chalcopyrite ore (density =
2.6 g/cu.cm) is roasted? Assume all the sulfur in
the ore is converted to SO2 and no other source of
sulfur is present.
