A 6.586-g sample containing magnesium chloride and sodium chloride was dissolved in sufficient water to give 500 mL of solution. Analysis for the chloride content of a 50.0-mL aliquot resulted in the formation of 0.5923 g of AgCl. The magnesium in a second 50.0-mL aliquot was precipitated as MgN H4 PO4 ; on ignition, 0.1796 g of Mg2P2O7 was found. Calculate the percentage of Mg Cl2 x 6H2O and of NaCl in the sample.
a. ________% MgCl2 x 6H2O
b. ________% NaCl
