Fe can be prepared as 2 Al + Fe2O3 ----> 2 Fe + Al2O3. Suppose that 0.450 moles of Fe2O3 are reacted with an excess of Al. Suppose that 43.6 grams of Fe are obtained. What is the percent yield of Fe?
Percent yield= actual yield of product divided by theoretical yield of product times 100.
The actual yield is stated to be 43.6 g of Fe, so I just need to know how to get the theoretical yield from the information it already gives me from the problem.
