### Formula

xi

mole fraction of the component i in the ideal solution

yi

mole fraction of the component i in the vapor

ptotal

total vapor pressure of the solution

pieqm

partial pressure of the component i in the ideal solution

xi

mole fraction of the component i in the ideal solution

yi

mole fraction of the component i in the vapor

ptotal

total vapor pressure of the solution

pieqm

partial pressure of the component i in the ideal solution

An ideal solution can be said to follow Raoult's Law but it must be kept in mind that in the strict sense ideal solutions do not exist. For a solution to be ideal we must assume that it does not matter whether a molecule A has another A as neighbor or a B molecule.
