Explain what is the average mass tablet

Reference no: EM13181247

Twenty dietary iron tablets with a total mass of 22.131g were ground and mixed thoroughly. Then 2.998 g of the powder were dissolved in HNO3 and heated to convert all iron into Fe3+. Addition of NH3 precipitated Fe2O3*xH2O, which was ignited to give 0.264g of Fe2O3 (FM 159.69). What is the average mass of Fe2SO4*7H2O (FM 278.01) in each tablet?
