CHEMISTRY - Calculating Copper Yield from Bornite Ore

[darthxepher]

Homework Statement

3) Bornite, Cu3FeS3, is an ore used in the production of copper. If 2.5kg of bornite produced a 60% yield, how much copper was collected?


2 Cu3FeS3(s) + 7 O2(g) ---> 6 Cu(s) + 2 FeO(s) + 6SO2(g)

The Attempt at a Solution

So first I calculated the moles of Cu3Fes3 and got about 7.3 moles. Then I am not sure what to do. Any suggestions?

Does no one hold the knowledge to answer my question?

 

[Borek]

So, how many moles of copper SHOULD be produced?
