PERCENT YEEEEEYEE YIELD

The theoretical yield of a reaction is the amount of products that SHOULD be formed. The actual amount depends on the experiment. The percent yield is like a measure of success.
                                                             -how close is the actual amount to the predicted amount?


actual / theoretical = percent % yield           theoretical-actual / theoretical = percent % error








                                      actual amount of product
percentage yield = ------------------------------------------- x 100
                                      expected amount of product

Example:  A student makes a single displacement reaction that produces 2.755 grams of copper. He determines that 3.150 grams of copper should have been produced. Find the student's percentage yield.

                     actual amount of product
percentage yield = ------------------------------------------- x 100
                           expected amount of product

  

                    2.755g

percentage yield = --------------- x 100
                           3.150g  

percentage yield = 87.4603174 %

percentage yield = 87.46 %

*remember!! 1. Recall definition of percent yield.

2. Substitute the actual and predicted yields.

3. Answer: what is the percent yield
