Please explain and show work step by step

Twenty dietary iron tablets with a total mass of 131 g were ground and mixed thoroughly. Then 2.998 g of the powder were dissolved in HN03 and heated to convert all the iron to Fe³⁺ . Addition of NH₃ caused quantitative precipitation of Fe₂O₃x H₂0, which was ignited to give 0.264 g of Fe₂O₃ ( FM 159.69). What is the average mass of FeS0₄^.7H₂0 ( FM 278.01) in each tablet?
