Asolution of methanol and water has a mole fraction of water of 0.312 and a total vapor pressure of 21 torr at 39.9 degrees c. the vapor pressures of pure methanol and pure water at this temperature are 256 torr and 55.3 torr , respectively.
is the solution ideal?
what can you say about the relative strengths of the solute-solvent interactions compared to the solute-solute and solvent-solvent interactions?
a. the methanol-water interactions are stronger than the methanol-methanol and water-water interactions.
b. the methanol-water interactions are weaker than the methanol-methanol and water-water interactions.
