Calculate the concentration of Solution B (KMnO₄) given titration data with Solution A (Na₂C₂O₄). If 0.76 g of Na₂C₂O₄ was used and the molar mass is 134.0 g/mol, what are the steps?

Here are the steps to calculate the concentration of Solution B (Potassium permanganate, KMnO₄) based on the provided data:

Objective: Determine the concentration of Solution B (KMnO₄) using the titration data with Solution A (Sodium oxalate, Na₂C₂O₄).

Assumption: The volume of Solution B (KMnO₄) pipetted into the conical flask for each titration was 25.00 cm³. This is a standard volume used in titrations when not explicitly stated.

Step 1: Calculate the molar mass of Sodium oxalate (Na₂C₂O₄)
Using atomic masses: Na = 23.0, C = 12.0, O = 16.0

$$\text{Molar mass of Na}_2\text{C}_2\text{O}_4 = (2 \times 23.0) + (2 \times 12.0) + (4 \times 16.0) = 46.0 + 24.0 + 64.0 = 134.0 \text{ g/mol}$$

Step 2: Calculate the moles of Sodium oxalate in 0.76 g
