A mixture of toluene (bp110.8C) and water is steam distilled. Visual inspection of the distillate reveals that there is a greater volume of toluene than water present, yet water (bp100C) has the higher vapor pressure. Explain this observation.
A volume of 7.32 L of air is bubbled through liquid toluene at 360. K, thus reducing the mass of toluene in the beaker by 11.2 g. Assuming that the air emerging from the beaker is saturated with toluene, determine the vapor pressure of toluene at this temperature.

Compound Chemical formula Hvap (kJ⋅mol−1) Boiling point (K) Hfus(kJ⋅mol−1) chloromethane CH3Cl 21.40 249.06 6.43 water H2O 40.65 373.15 6.01 hydrogen sulfide H2S 18.67 213.60 18.67 1. Trouton's rule states that the molar enthalpy of vaporization of a liquid that does not have strong molecular interactions such as hydrogen bonding or ion‑ion attractions is given by Hvap=(85 J⋅K-1⋅ mol-1)Tb Where Tb is the normal boiling point of the liquid in kelvins.
