Chalcopyrite, CuFeS2, is an important source of copper. A typical chalcopyrite ore contains about 0.75% Cu. What volume of sulfur dioxide at 25°C and 1.00 atm pressure is produced when one boxcar load (4.00 × 103 ft3) 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
