20.0 cm3 of a H2C2O4 solution required 8.60 cm³ of a 0.2010 M solution of sodium hydroxide for complete neutralization using phenolphthalein indicator (first permanent pink end-point). 20.0 cm3 of the same H2C2O4 solution required 7.85 cm³ of a KMnO4 solution to reach the permanent pink endpoint. Calculate the molarity of both the H2C2O4 solution and KMNO4 solution.
