Calculate the concentration of potassium permanganate. I don't understand this at all!
I so far have the equation .. of
OA: MnO4 + 8H + 5e -> Mn2+ + 4H2O
SA: Fe2+ -> Fe 3+ + e-
net: MnO4 + 8H + 5Fe -> Mn2+ + 4H2O + 5Fe
and i dont know where to go from there .

To know the conc of KMnO4 you need to tell vol of Fe++ and normality of Fe++ then only you can solve the problem by using
N1V1=N2V2 and Conc =eq.wt x Normality
