Raoult's Law states that the vapor pressure of a solvent in a solution is directly proportional to the mole fraction of the solvent present. This principle is crucial in understanding how temperature, pressure, and composition scales influence the behavior of mixtures, especially when dealing with ideal solutions. By using Raoult's Law, one can predict how the addition of a solute affects the vapor pressure of a solvent, making it essential for calculations involving phase equilibria.
