CHEMISTRY - Reaction Problem

  1. Sep 17, 2009 #1
    1. The problem statement, all variables and given/known data

    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)





    3. 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?

    So, how many moles of copper SHOULD be produced?
