Explanation Given Density of pure benzene is 0.8765 g/cm 3 . Vapor pressure of pure benzene is 100.0 torr . Volume of pure benzene (solvent) is 10 0 mL . Vapor pressure of the solvent is decreased by 10 % , on adding non-volatile solute to the pure benzene (solvent). Hence, vapor pressure of solution is calculated as, Pressure of solution = P solvent ∘ − 10 % × P solvent ∘ Where, P solvent ∘ is the vapor pressure of pure solvent. Substitute the value of P solvent ∘ in the above equation. Pressure of solution = 100 torr − 10 % × 10 0 torr = 100 torr − 10 100 × 100 torr = 9 0 torr Mole fraction of benzene (solvent) is calculated by the formula, P solution = Mole fraction of benzene×P solvent ∘ Mole fraction of benzene = P solution P solvent ∘ Where, P solution is the vapor pressure of solution. Substitute the value of P solution and the P solvent ∘ in the above equation. Mole fraction of benzene = 90.0 torr 100 torr = 0
