potassium permanganate was used to determine the percentage of iron (Fe, At weight: 55.845? in an ore sample. the procedure included dissolving the iron wiht HCl and then converting all the iron in the ore to Fe2+ using several reagents. Once completing the conversion, titrated the following resulting Fe2+ with MnO4-:

Fe2+ + MnO4- --> Fe3+ + Mn2+ ( unbalanced)

The sample of the original ore was 3.852g and was processed for titration in the a total volume of 150.0 ml solution. a 50.0 ml aliquot of this solution was used for the titration with a .0512 M KMnO4 solution. A total of 46.2 mL was required to obtain the light purple-pink endpoint. what is the percent of iron in the ore sample?
