The active ingredient in a zinc nutritional supplement is ZnSO, · 7 H,O (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 11.825 g. A 2.206 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 (NH),PO, to the solution resulted in the precipitation of ZNNH¸PO,. The precipitate was filtered and dried, then ignited to produce 0.244 g of Zn, P,O, (molar mass = 304.76 g/mol). What is the mass percent of ZnSO. · 7 H,O in each tablet? mass percent: % ZnSO, · 7 H,O What is the average mass of the active ingredient ZNSO̟ · 7 H,O and inactive filler in each tablet? g ZnSO, · 7 H,O mass: mass: g inactive filler

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?

The active ingredient in a zinc nutritional supplement is ZnSO₄ · 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 11.825 g. A 2.206 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 to the solution resulted in the precipitation of ZnNH₄PO₄. The precipitate was filtered and dried, then ignited to produce 0.244 g of Zn₂P₂O₇ (molar mass = 304.76 g/mol). What is the mass percent of ZnSO₄ · 7H₂O in each tablet?
