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 Molar mass of Na_2C_2O_4 = (2 × 23.0) + (2 × 12.0) + (4 × 16.0) = 46.0 + 24.0 + 64.0 = 134.0 g/mol Step 2: Calculate the moles of Sodium oxalate in 0.76 g Moles of Na_2C_2O_
