Chapter 4, Problem 131CP

A sample is a mixture of ${\text{AgNO}}_{\text{3}}{\text{, CuCl}}_{\text{2}}{\text{, and FeCl}}_{\text{3}}$ .When a 1.0000-g sample of the mixture is dissolved inwater and reacted with excess silver nitrate, 1.7809 g ofprecipitate forms. When a separate 1.0000-g sample ofthe mixture is treated with a reducing agent, all themetal ions in the mixture are reduced to pure metals.The total mass of pure metals produced is 0.4684 g.Calculate the mass percent of ${\text{AgNO}}_{\text{3}}{\text{, CuCl}}_{\text{2}}{\text{, and FeCl}}_{\text{3}}$ in the original mixture.
