Mole fraction of a component in solution by Raoult's law and Dalton's law
mole fraction of the component i in the ideal solution
mole fraction of the component i in the vapor
total vapor pressure of the solution
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.
