Chalcopyrite, CuFeS₂, is an important source of copper. A typical chalcopyrite ore contains about 0.75% Cu. What volume of sulfur dioxide at and 1.00 atm pressure is produced when one boxcar load (4.00 × 10³ ft ³) of chalcopyrite ore (d = 2.6 g/cm³) is roasted? Assume all the sulfur in the ore is converted to SO₂ and no other source of sulfur is present.
