Acetylene gas may be produced by carefully adding water to calcium carbide, according to the equation:

CaC2(s) + 2 H2O(l) → Ca(OH)2(s) + C2H2(g)

When a 37 g sample of an impure calcium carbide was treated with excess water, 13 g of acetylene gas was produced. If the reaction is essentially 100% efficient, what was the percentage of nonreacting impurity in the carbide sample?
◦ 86%
◦ 58%
◦ 42%
◦ 35%
◦ 13.5%
