Identify the correct statements : A. The molality of 10 g of glucose (Molar mass : 180 g mol ⁻¹ ) in 250 g of water is 0.222 m. B. The molarity of a solution containing 4.9 g of H₂SO₄ (molar mass : 98 g mol ⁻¹ ) in 500 mL of solution is 0.1 M. C. The solubility of gases in liquids generally decreases with an increase in temperature. D. Higher the value of Henry's law constant ( K_H ) at a given pressure, higher is th

Step-by-step solution

Statement A: Molality m = Moles of solute Mass of solvent in kg = 10 / 180 250 / 1000 = 1 18 4 = 0.222 m. Statement A is correct. Statement B: Molarity M = Moles of solute Volume of solution in L = 4.9 / 98 500 / 1000 = 0.05 0.5 = 0.1 M. Statement B is correct. Statement C: Dissolution of a gas in a liquid is an exothermic process. By Le Chatelier's principle, the solubility of gases in liquids generally decreases with an increase in temperature. Statement C is correct. Statement D: According to Henry's law, p = K_
