Step 3 Calculate the theoretical yield Our final step is to determine the theoretical yield of AlCl 3 in the reaction Remember that the theoretical yield is the amount of product that is produced when the limiting reactant is fully consumed In this case the limiting reactant is Cl A 2 so the maximum amount of AlCl 3 that can be formed is Find the limiting reagent 54g Al x 1 mole Al 27g Al 2 mole Al 319g CuSO4 x I mole CuSO4 159 5g CuSO4 2 mole CuSO4 limiting reagent 2 mole CuSO4 x 3 mole Cu 3 mole CuSO4 x 63 5g Cu 1 mole Cu 127g Cu Multiply the founded limiting reagent with moles of Copper 3 over moles of CuSO4 3 from the equation to cancel out moles of CuSO4
