Sodium oxalate, Na2C2O4, in solution is oxidized to CO2(g) by MnO4– which is reduced to Mn2+. A 50.2-mL volume of a solution of MnO4– is required to titrate a 0.340-g sample of sodium oxalate. This solution of MnO4– is then used to analyze uranium-containing samples. A 4.63-g sample of a uranium-containing material requires 33.0 mL of the solution for titration. The oxidation of the uranium can be represented by the change UO2+ → UO22+. Calculate the percentage of uranium in the sample.
