In a volumetric analysis experiment, a solution of sodium oxalate in acidic soltuion is titrated with a solution of potassium permanganate according to the following balanced chemical equation:
2KMnO4+8H2SO4+5Na2C2O4 -> 2MnSO4+8H2O+10CO2+5Na2SO4+K2SO4
What volume of .0239 M KMnO4 is required to titrate .128 g of Na2C2O4 dissolved in 35 mL of solution?
