← The osmotic pressure of a solution of 0.54 g of a polymer in 180 mL of solution is 0.15 kPa at 27 °C. What is the molar mass of the polymer? Take R = 8.314 J K⁻¹mol⁻¹.The vapour pressure of a pure solvent is 38.4 kPa. Above a solution of a non-volatile solute in it, the pressure is 35.3 kPa at the same temperature. What is the mole fraction of the solute in the solution? →
