← A solution of 0.95 g of magnesium chloride, of molar mass 95 g/mol, in 125 g of water is taken to split completely. What is its freezing point? Take Kf = 1.86 K kg/mol.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? →
