2. a certain copper ore contains 3.76% of cu2s by mass, and the remainder of the ore contains no copper. in a particular year, a single open-air smelt furnace heated 22000 tons of this ore. compute the maximum mass of copper metal that could have been obtained by this process. (clarification: the tons in this problem are english tons, with 1 ton = 2000 lb. you can answer in g, kg, or lb, but the computer does not understand tons as a unit for the answer.)
