Chapter 3, Problem 85E

Bornite ${\text{(Cu}}_{\text{3}}{\text{FeS}}_{\text{3}}\text{)}$ is a copper ore used in the productionof copper. When heated, the following reaction occurs:

${\text{2Cu}}_{\text{3}}{\text{FeS}}_{\text{3}}\text{(}s{\text{)+7O}}_{\text{2}}\text{(}g\text{)}\to \text{6Cu(}s\text{)+2FeO(}s\text{)+6SO2(}g\text{)}$

If 2.50 metric tons of bornite is reacted with excess ${\text{O}}_{\text{2}}$ and the process has an 86.3% yield of copper, how muchcopper is produced?
