The vapor pressure of an organic solvent is 50mmHg at 25 C and200mmHg at 45 C. The solvent is
the only species in a closed flask at 35 C and is present in bothliquid and vapor states. The volume
of gas above the liquid is 150 mL.
a) Estimate the amount of the solvent (mol) contained in the gasphase.
b) What assumptions did you make? How would you answer change ifthe species dimerized (one molecule results from two molecules ofthe species combining?
