In acidic solution, sodium oxalate, Na2C2O4, is oxidized to CO2 by MnO4. In the process, MnO is reduced to Mn²+. To titrate a 0.518 g sample of Na2C2O4, 42.5 mL of an MnO4 solution were required. The same MnOд solution is then used to analyze samples that contain uranium. A 11.9 g sample of a material that contains uranium required 32.9 mL of the MnO solution for titration. During titration, the uranium sample was oxidized as shown. UO2+(aq) UO2+(aq) Calculate the mass percent of uranium in the sample. mass percent of uranium: do %
