    The heat of vaporization of methanol is 35.2 kJ mol-1. If the boiling point of methanolis 338 K, calculate the vapour pressure of methanol at 273 K

    For this I was going to use clapeyron equation but there's no pressure given so i'm not sure what to do

    Bearing in mind I haven't had to touch a problem like this for 2 years.... I'm thinking you need to balance the chemical potentials of both phases.
