How to calculate theoretical yield of CuCl_2 + Fe rarr Cu + FeCl_2?

I already found the theoretical yield for Cu, because of a percent yield question, but this question wants the theoretical yieled for the overall reaction?

$C u C {l}_{2} \left(a q\right) + F e \left(s\right) \to C u \left(s\right) + F e C {l}_{2} \left(a q\right)$
