Chalcopyrite (C'uFeS2), 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 atm pressure is produced when one boxcar load ( 4 x 103 ft³) of chalcopyrite ore (density = 2.6 -) is roasted? Assume all the ст3 sulfur in the ore is converted to SO2 and no other source of sulfur is present.
