A powder contains FeSO4 7 H,O (molar mass = 278.01 g/mol), among other components. A 3.995 g sample of the powder was dissolved in HNO2 and heated to convert all iron to Fe3*. The addition of NH3 precipitated Fe,O2 - xH,O, which was subsequently ignited to produce 0.210 g Fe2O3. What was the mass of FeSO4 7H,0 in the 3.995 g sample? mass of FeSO4 7H,O: ge
