Chapter 5, Problem 125E

Bornite (Cu₃FeS₃) is a copper ore used in the production of copper. When heated, the following reaction occurs:

$2{\text{Cu}}_{\text{3}}{\text{FeS}}_3\left(s\right)+{\text{ 7O}}_{\text{2}}\left(g\right)\to 6\text{Cu}\left(s\right)+2\text{FeO}\left(s\right)+6{\text{SO}}_2$

If 2.50 metric tons of bornite is reacted with excess O₂ and the process has an 86.3% yield of copper, what mass of copper is produced?
