The normality of a solution is calculated based on the equivalent weight of the solute and the volume of the solution. The given compound is H₂SO₄ (sulfuric acid), which has a molar mass of approximately 98 g/mol. Since 49 g of H₂SO₄ is used, this corresponds to 0.5 moles of H₂SO₄. Sulfuric acid is a diprotic acid, meaning it can donate two protons per molecule. Therefore, the number of equivalents is 0.5 moles * 2 = 1 equivalent. The volume of the solution is 400 mL or 0.4 L. Normality (N) is defined as the number of equivalents per liter of solution, so the normality of this solution is 1 equivalent / 0.4 L = 2.5 N.
