I need help with calculations related to an experiment. I'm missing experimental data like masses, volumes, and titration results for KMnO4. Can you help me solve it?

I can help you with these calculations, but the image provided does not contain the necessary experimental data (like the mass of oxalate used, the volume of the oxalate solution, or the titration volumes for $\text{KMnO}_4$) to answer questions 1, 2, and 3.

Please provide the relevant data, possibly from a table or a previous part of the experiment, so I can proceed with the calculations.
