How to calculate amount of ores?

A certain mine produces 2.0 108 kg of copper from chalcopyrite (CuFeS2) each year. The ore contains only 0.90% Cu by mass.
(a) If the density of the ore is 2.6 g/cm3, calculate the volume of ore removed each year.

(b) Calculate the mass of SO2 produced by roasting (assume chalcopyrite to be the only source of sulfur).
