A 25.0 mL aliquot of an FeSO4 solution is titrated against standard 0.0100M K2Cr2O7 solution using diphenylmethane indicator. At the end point 23.oo mL of K2Cr2O7 solution have been consumed. Calculate the normality and the molarity of of the FeSO4 solution. (Hint: Cr2O^-2 is reduced to Cr^3+ while Fe^2+ is oxidized to Fe^3+).
