Copper oxide ore, CuO, can be smelted with carbon to make copper metal and carbon dioxide. $2 \mathrm{CuO}(s)+C(s) \rightarrow 2 \mathrm{Cu}(s)+\mathrm{CO}_{2}(g)$ If 100.0 of a mixed ore is smelted and produces 75.9 grams of pure copper. What percentage of the mixed ore is CuO?
(You can assume the reaction yield is 100%, there is excess carbon, and that CuO is the only source of copper.)
