Mole fraction of a component in solution by Raoult's law and Dalton's law
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
Formula description
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.
