a) There is a sample that contains the mixture of CuCl2(s) and KCl(s) with a mole fraction of 6.90% KCl was dissolved in water. Access of AgNO3(s) was added to the mixture, resulting in all the chloride being precipitated as AgCl(s). The AgCl(s) was collected and dried, then weighted to have a mass of 4.20g. Calculate the masses of the KCl(s) and CuCl2(s) in the original mixture.
