A sample containing a mixture of CuCl2(s) and KCI(s) with a mole fraction of 13.8% KCI was dissolved in water. An excess of AgNO3(s) is added to the mixture, resulting in the chloride being precipitated as AgCl(s). The AgCl(s) is collected and dried, weighed to have a mass of 8.40g. Calculated the masses of KCI(s) and CuCl2(s) in the original mixture.
