    This project was preformed to supply Libretext Authors with videos on General Chemistry topics which can be used to enhance their projects.  Also, these videos are meant to act as a learning resource for all General Chemistry students.

    A nonionic-volatile solute will also cause the vapor pressure of the solvent to decrease. However, because the solute is volatile it will also have a vapor pressure. To find the overall vapor pressure of the solution the vapor pressure of the solute and the solvent must be combined.

    Raoult's Law Pa = XaPao
    Pa = Vapor pressure of a liquid in a solution
    Xa = Mol fraction of the liquid in the solution
    Pao = Vapor pressure of the pure solvent
    Because the solute is volatile we must consider the vapor pressure of both the solute and the solvent. Psolution = Psolute + Psolvent .
