The active ingredient in a zinc nutritional supplement is ZnSO4⋅7H2OZnSO4⋅7H2O (molar mass = 287.58 g/mol). Ten zinc tablets containing a mix of the active ingredient and an inactive filler were ground and mixed together thoroughly. The total mass of these 10 tablets was 11.82511.825 g. A 2.2062.206 g sample of the finely ground tablets was dissolved in an acidic solution. The solution was neutralized with ammonia and subsequently warmed in a water bath. Addition of (NH4)3PO4(NH4)3PO4 to the solution resulted in the precipitation of ZnNH4PO4ZnNH4PO4. The precipitate was filtered and dried, then ignited to produce 0.2440.244 g of Zn2P2O7Zn2P2O7 (molar mass = 304.76 g/mol). What is the mass percent of ZnSO4⋅7H2OZnSO4⋅7H2O in each tablet?
