19.193 g of a non-volatile solute is dissolved in 180.0 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 20°C the vapour pressure of the solution is 17.242 torr. The vapour pressure of pure water at 20°C is 17.535 torr. Calculate the molar mass of the solute (g/mol). Now suppose, instead, that 19.193 g of a volatile solute is dissolved in 180.0 g of...
