A 0.703 g sample of a commercial detergent was red-calcined to destroy its components. organic. Treatment of the residue with hot HCl gave phosphorus in solution as H3PO4. the phosphate was precipitated as MgNH4PO4-6H2O by the addition of Mg + 2 or followed by aqueous NH3. The precipitate was filtered, washed, and converted to Mg2P2O7 by calcination at 1000 C. The residue weighed 0.432 g. Calculate the percentage of phosphorus in the sample.
