A 644.0 g sample containing magnesium sulfate and inert material was dissolved and treated with (NH4)2HPO4 to precipitate the magnesium as MgNH4PO4. 6H2O. After being filtered and washed, the precipitate was ignited at 10500C to Mg2P2O7 that, upon cooling, weighed 293.0 mg. Calculate the % Mg in the sample.
