A solid sample containing some Fe(2+) ion weighs 1.923 grams. It requires 36.44 mL 0.0244 M KMnO4 to titrate Fe in the dissolved sample to a pink end point. Chemical equation: 8H(+) + MnO4(-) + 5Fe(2+) --> Mn(2+) + 4H2O + 5Fe(3+) How many moles MnO4(-) ion are required? How many moles Fe(2+) are there in the sample? How many grams of iron are in the sample? Whats the percentage of Fe in the sample?
