A mixture contains only and . A 4.51-g sample of the mixture is dissolved in water and an excess of is added, producing a precipitate of . The precipitate is filtered, dried, and weighed. The mass of the precipitate is 1.06 g. What is the mass percent of in the sample?

%

Solutions

Expert Solution

mass percent of precipitate in the sample = mass of precipitate / mass of sample *100

                                                                 = 1.06/4.51*100

                                                                  = 23.5%
