A solid sample containing some Fe2" ions had a total mass of 0.9 g. It required 19.4 mL 0.02124 M KMNO4 to titrate the Fe2" in the dissolved sample to a pink end point for the following reaction: 8 H*(aq) + Mn04" (aq) + 5 Fe2* (aq) → 5 Fe3* (aq) + Mn2* (aq) + 4 H20(1) How many moles of MnO4 ion were required? mol How many moles of Fe2t were present in the sample? mol How many grams of iron were present in the sample? What was the mass percent of iron in the sample?
