Chemistry
The active ingredient in a zinc nutritional supplement isZnSO4·7H2O (molar mass = 287.58 g/mol). Ten zinc tablets containinga mix of the active ingredient and an inactive filler were groundand mixed together thoroughly. The total mass of these ten tabletswas 10.165 g. A 1.830 g sample of the finely ground tablets wasdissolved in an acidic solution. The solution was neutralized withammonia and subsequently warmed in a water bath. Addition of(NH4)3PO4 to the solution resulted in the precipitation ofZnNH4PO4. The precipitate was filtered and dried, then ignited toproduce 0.234 g of Zn2P2O7 (molar mass = 304.76 g/mol). What is themass percent of ZnSO4·7H2O in each tablet?
What is the average mass of the active ingredient ZnSO4·7H2O andinactive filler in each tablet?
