here is the steps that how to solve it
For solutions that contain non-volatile solutes, the vapor pressure of the solution can be determined by using the mole fraction of the solvent and the vapor pressure of the pure solvent at the same temperature.
Psol=χsolvent⋅P∘solvent , where
Psol is the vapor pressure of the solution
χsolvent is the mole fraction of the solvent
P∘solvent is the vapor pressure of the pure solvent
