Vapour pressure of pure A = 100 torr, moles = 2; vapour pressure of pure B=80 torr, moles = 3. Total vapour pressure of the mixture is

View answer and explanation

Correct option: D

88 torr

Option D (88 torr) is correct because it is calculated using Raoult's Law to find the total vapor pressure of the mixture.
