← At 20 °C, pure pentane has a vapour pressure of 58 kPa and pure hexane has 16 kPa. They form a nearly ideal solution in which the mole fraction of pentane is 0.45. What is the mole fraction of pentane in the vapour above it?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. →
