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.
