A salt unknown containing ferrous ion was dissolved and diluted to 407.8 mL. A 47.56- mL aliquot of the ferrous ion solution was titrated with 0.6961 M potassium permanganate solution, and the mean of three acceptable, blank-corrected titrations volumes was 16.34 mL. Calculate the mass of iron in the original solution. Give your answer to two places after the decimal. Do not enter units. The unbalanced reaction between ferrous and permanganate which requires an acidic medium is: Fe?+ + MnO, → Fe3+ + Mn²+
