O Macmillan Learning A powder contains FeSO4 · 7 H₂O (molar mass = 278.01 g/mol), among other components. A 3.665 g sample of the powder was dissolved in HNO3 and heated to convert all iron to Fe³+. The addition of NH3 precipitated Fe₂O3 xH₂O, which was subsequently ignited to produce 0.342 g Fe₂O3. What was the mass of FeSO4.7H₂O in the 3.665 g sample? mass of FeSO4.7H₂O: 0.76 Incorrect g
