A solution is prepared by mixing 75 g of benzene (C6H6) with 25 g of toluene (C7H8). Use the following data to determine the vapor pressure of this solution at 20C. (Hint: Calculate the vapor pressure of each substance in solution separately, then add them together to get the total vapor pressure of the solution.)
Vapor Pressure at 20C (torr)
Benzene 75
Toluene 22

a. 35 torr
b. 87 torr
c. 63 torr
d. 71 torr
e. 49 torr

    In a mixture of volatile substances, the vapor pressure of the solution depends on the vapor pressure of both substances (solute and solvent). Each component can evaporate, but its vapor pressure is lowered by the presence of the other substance following Rault's law. The vapor pressure of the solvent is calculated using Psolvent = Xsolvent*Posolvent and the vapor pressure of the solute is calculated using Psolute = Xsolute*Posolute. The total vapor pressure can be calculated by Dalton's law of partial...
