Transcribed Image Text:In acidic solution, sodium oxalate, Na₂C₂O4, is oxidized to CO₂ by MnO4. In the process, MnO, is reduced to Mn² +.
To titrate a 0.855 g sample of Na₂C₂O₁, 43.7 mL of an MnO solution were required. The same MnO solution is then used to
analyze samples that contain uranium. A 12.8 g sample of a material that contains uranium required 29.3 mL of the MnO,
solution for titration. During titration, the uranium sample was oxidized as shown.
UO² (aq) → UO *(aq)
Calculate the mass percent of uranium in the sample.
mass percent of uranium:
