(a) 1.28 g of potassium chloride dissolved in 12.5 g of water % (b) 1.28 g of potassium chloride dissolved in 25.0 g of water (c) 1.28 g of potassium chloride dissolved in 37.5 g of water % (d) 1.28 g of potassium chloride dissolved in 50.0 g of water %
1a: 19.930 g of a non-volatile solute is dissolved in 395.0 g of water. The solute does not react with water nor dissociate in solution. Assume that the resulting solution displays ideal Raoult's law behaviour. At 90°C the vapour pressure of the solution is 521.11 torr. The vapour pressure of pure water at 90°C is 525.80 torr. Calculate the molar mass of the solute (g/mol). 1b: Now suppose, instead, that 19.930 g of a volatile solute is dissolved in 395.0...
