Solve it in a step by step way I can understand and it should be in English

This image describes the procedure for standardizing potassium permanganate and then determining the concentration of oxalic acid. However, it does not contain the actual data from "Table 1" and "Table 2" (titration results) or the exact mass of ammonium iron (II) sulphate used.

To solve any quantitative questions related to this experiment (e.g., calculating concentrations), I need the following information:

1. The exact mass of solid ammonium iron (II) sulphate weighed out (between 4.80 - 4.85 g).
2. The titration results from Table 1, which show the volume of $\text{KMnO}_{4}$ used to react with the iron (II) solution.
3. The titration results from Table 2, which show the volume of $\text{KMnO}_{4}$ used to react with the oxalic acid solution.

Please provide these tables or the specific data points so I can proceed with the calculations!
