    1. Calculations Given the following data, determine the % by mass of oxalate (C2O42-) in a sample of an iron oxalate complex with the general formula Kz[Fex(C2O4)y].wH2O. The reaction between oxalate and permanganate is as follows: 6H+ + 5(COOH)2 + 2MnO4- → 10CO2 + 2Mn2+ + 8H2O m(iron oxalate complex) used for titration = 0.100 g C(KMnO4) standard solution = 0.0200 M M(C2O42-) = 88.02 g mol-1 Titre volume = 10.18 mL Enter your answer to 3 significant figures. 2....
