A sample contains MgCl2 (95.211 g/mol) and KCl (74.551 g/mol). A 6.6933-g sample was dissolved in enough H2O to make 250.0-mL solution. A 50.00-mL aliquot was treated with AgNO3 to precipitate the chlorides and after proper collection and drying gave a precipitate weighing 1.9620-g. Another 50.00-mL aliquot was tested for its Mg2+ content by precipitating it with NH4+ and PO43- giving an Mg2P2O7 (222.551 g/mol) precipitate weighing 0.5186 g with FW AgCl 143.32 g/mol.
