Aluminum reacts with excess copper(II) sulfate according to the unbalanced reaction
Al(s) + CuSO4(aq) −→
Al2(SO4)3(aq) + Cu(s)
If 2.21 g of Al react and the percent yield of
Cu is 40.8%, what mass of Cu is produced?
Answer in units of g.
I got 7.807423031 g of Cu.
Is that correct?
I didn't come up with that answer. Did you balance the equation?
2Al + 3CuSO4 ==> 3Cu + Al2(SO4)3
