A sample is a mixture of AgNO₃, CuCl₂, and FeCl₃. When a 1.0000- g sample of the mixture is dissolved in water and reacted with excess silver nitrate, 1.7809 g of precipitate forms. When a separate 1.0000- g sample of the mixture is treated with a reducing agent, all the metal 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 AgNO₃, CuCl₂, and FeCl₃ in the original mixture.
