1.a A 2.5600 g sample of a compound that containssulfur is analyzed by precipitating all the sulfuras BaSO4. If 1.326 gof BaSO4 are obtained in the analysis, what isthe percentage of sulfur in the original compound?
b.One way to analyze for the amount of phosphorus in a rockis to precipitate the phosphorusas MgNH4PO4, which is then heated toturn itinto Mg2P2O7. Whatweight of Mg2P2O7 willbe obtained from a 3.831 g sample of a rock that contains86.52% Ca3(PO4)2 (and noother source of phosphorus) if this analysis is done?
