If a Sodium oxalate, Na2C2O4,in solution is oxidized to CO2(g) by MnO4(-) which is reduced to Mn(2+) . A 50.3mL volume of a solution of MnO4(-) is necessary to titrate a 0.340g sample of sodium oxalate. This solution of MnO4(-) is then utilized to analyze uranium-containing samples. A 4.62g example of a uranium-containing material needs 32.0 mL of the solution for titration. Define the oxidation of the uranium can be represented by the change UO(2+) --> UO2(2+). Compute the percentage of uranium in the sample
