Vapour Pressure of Solutions of Non-Volatile or Volatile Solutes 14.356 g of a non-volatile solute is dissolved in 265.0 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 17.396 torr. The vapour pressure of pure water at 20°C is 17.535 torr. Calculate the molar mass of the solute (g/mol). See example 17.1 on pp718-9 of Zumdahl "Chemical Principles" 8th ed. 1pts Submit Answer Tries 0/5 Now suppose, instead, that 14.356 g of a volatile solute is dissolved in 265.0 g of water. This solute also does not react with water nor dissociate in solution. The pure solute displays, at 20°C, a vapour pressure of 1.754 torr. Again, assume an ideal solution. If, at 20°C the vapour pressure of this solution is also 17.396 torr. Calculate the molar mass of this volatile solute. cf p 719 of Zumdahl "Chemical Principles" 8th ed.
