Given the following data, determine the % by mass of oxalate (C204²) in a sample of an iron oxalate complex with the general formula K2[Fe,(C204)yl.WH2O. The reaction between oxalate and permanganate is as follows: 6H* + 5(COOH)2 + 2MnO4¯ → 10CO2 + 2Mn²* + 8H20 m(iron oxalate complex) used to make up 25.00 mL of solution: 0.25 g Volume of iron oxalate solution used for titration: 2.000 mL C(KMNO4) standard solution = 0.0200 M M(C204²) = 88.02 g mol1 Titre volume = 2.21 mL Enter your answer to 3 significant figures. Do not enter units. Very large or small numbers can be entered in scientific notation - for example enter 1.23E- 4 to represent 1.23x104.
