Vapour pressure of solution containing 2 mol of liquid A (${\mathrm{P}}_{\mathrm{A}}^{\circ }$ = 80 torr ) and 3 mot of liquid B (${\mathrm{P}}_{\mathrm{B}}^{\circ }$ = 100 torr ) is 87 torr. We can conclude that

there is negative deviation from Raoult's law

boiling point is higher than that expected for ideal solution

molecular attractions between unlike molecules are stronger than those between like molecules

all of these statements are correct
