The active ingredient in a zinc nutritional supplement is Znso4- 7H20 (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 ten tablets was 10.830 g. A 2.402 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 0.264 g of ZngP207 (molar mass = 304.76 g/mol). What is the mass percent of ZNSO4 7H2O in each tablet? Number % ZnSO, 7H,0 What is the average mass of the active ingredient ZnSO4: 7H20 and inactive filler in each tablet?
