Solved: A certain mine produces 2.0 × 108 kg of copper
Chapter 21, Problem 16P(choose chapter or problem)
A certain mine produces \(2.0 \times 10^{8} \ \mathrm{kg}\) of copper from chalcopyrite \(\left(\mathrm{CuFeS}_{2}\right)\) each year. The ore contains only 0.80 percent Cu by mass. (a) If the density of the ore is \(2.8\mathrm{\ g}/\mathrm{cm}^3\), calculate the volume (in \(\mathrm{cm}^3\)) of ore removed each year. (b) Calculate the mass (in kg) of \(\mathrm{SO}_{2}\) produced by roasting (assume chalcopyrite to be the only source of sulfur).
