Sodium oxalate, Na2C2O4, in solution is oxidized to CO2 by MnO4- which is reduced to Mn2+. A 50.1 volume of a solution of MnO4- is required to titrate a 0.339 g sample of sodium oxalate. This solution of MnO4- is then used to analyze uranium-containing samples. A 4.62 g sample of an unknown uranium-containing material requires 32.5 mL of the solution for titration. The oxidation of the uranium can be represented by the change UO2+->UO(subscript)2 2+

Calculate the percentage uranium in the sample.
