Fe2+ A 0.1283 g sample of M3Fe(C2O4)3 was dissolved in dilute acid, and all of the iron was converted to ions. This acidic solution required 20.55 mL of 0.02000 M KMnO4 solution to reach the end point of this titration, in which the products were Fe³+ (aq), Mn²+ (aq) and CO2 (g). (a) Calculate the molar mass of M3Fe(C204)3. (b) What fraction of the total KMnO4 solution was used in the titration of the oxalate ions (C2O4²-) in the titration in part (a)?
