Here is an example stoichiometry problem I've posted. Just follow the steps. Also, remember to type the arrow somewhere so you can tell the difference between products and reactants.

2Al + 3CuSO4 ! Al2(SO4)3 + 3Cu
What is the maximum amount of Cu (63.5
g/mol) that could be produced by reacting
20.0 grams of Al (27.0 g/mol) with excess
CuSO4?
