To calculate the percent yield, you divide the actual yield by the theoretical yield and multiply by 100.

*EXAMPLE*

What is the percent yield if 0.650 g of copper are formed when excess aluminum reacts with a 2.00 g of copper(II) chloride dihydrate according to the equation

3CuCl₂•2H₂O + 2Al → 3Cu + 2AlCl₃ + 2H₂O

*Solution*

First, calculate the theoretical yield of Cu.

2.00 g CuCl₂•2H₂O ×

0.745 g Cu

Now calculate the percent yield.

% yield = (actual yield)/(theoretical yield) × 100 % =
