At 20◦C the vapor pressure of pure methanol
(CH3OH) is 89.0 torr and of pure water (H2O)
is 17.5 torr. A solution of methanol and water
has a total vapor pressure of 35.5 torr at
20◦C. Calculate the mole fraction of methanol
in this solution. Assume the solution obeys
Raoult’s Law

I missed the first day of class of the new unit due to blood donation and I honestly hardly even know where to start with the question this time. Any help would be appreciated
