Calculations: Practical Yield and % Yield



                 Practical (Actual) Yield                                      % Yield
          ◼  The actual yield is the amount of             ◼  Chemists spend a lot of time and money


             product produced by a reaction.                   improving their percent yield.
          ◼  It may be higher than a theoretical           ◼  % Yield =                                                  (  )   ×       
                                                                                                                            (  )
             yield because:
                                                                          = ⋯ %
              1.  The recovered product contains


                  impurities that increase the

                  product's weight.

          ◼  In order to obtain the practical yield

             you should purify, dry then weigh the

             product.
