Suppose you react 81 grams of Al (atomic mass = 27 g/mol) with 213 grams of Cl2 (M.W. = 71 g/mol), and you obtain 133.5 grams of AlCl3, according to the following equation:
1. The limiting reactant?
2. The theoretical yield?
3. The percent yield?
4. How many grams of the excess reagent are left over, once the reaction is completed?
