Created by StemPy LabSugar dissolves in water and never evaporates. At one temperature, the vapour pressure above a sugar solution is lower than above pure water. Which explanation is right?

← Liquid P has a vapour pressure of 60 kPa at 320 K, and liquid Q has 20 kPa at the same temperature. In an ideal liquid solution of the two, 45 % of the molecules are P. How much pressure does P alone give in the vapour?A solvent has a vapour pressure of 45 kPa at a certain temperature. A solute that cannot evaporate is added until its mole fraction is 0.06. What does the vapour pressure of the solution become? →
