Explanation / Answer

1) To find the average mass of zinc sulfate heptahydrate or (ZnSO4*7H2O) in each tablet, we need to calculate the mass of each tablet.

Mass of each tablet= total mass of the ground tablets/ number of tablets used

2)   As % of ZnSO4·7H2O in each tablet=24.13%(m/m)

So , average mass of the active ingredient ZnSO4·7H2O=24.13% of mass of one tablet=24.13/100* mass of 1 tablet

3) To find the mass of the inactive filler ,

Mass of inactive filler=mass of one tablet- average mass of the active ingredient ZnSO4·7H2O(calculated in part 2)
