Fifty iron supplement tablets with a total mass of 35.211g were ground and mixed thoroughly. Then 5.00g of the powder were dissolved in HNo3 and heaated to convert all iron into Fe3+. Addition of NH3 precipitaed Fe2O3*xH2O, which was ignited to give 0.0531g of Fe2O3. Solve using gravimetric calculation and show the complete soluition in paper A. What is the percentage of FeSO47H2O in the sample? B. What is the average mass of FeSO47H2O in each tablet?
