For example, the mixture of chloroform (ch 3 cl) and acetone (ch 3 coch 3 ), presents a negative deviation from raoult's law. In our raoult's law example above, our solute, sugar, doesn't produce any vapor on its own at normal temperatures (think — when was the last time you saw a bowl of sugar evaporate on your counter top?) however, when your solute does evaporate, this will affect your vapor pressure. Use raoult's law to determine the vapor pressure of a solution. At a certain temperature, the pure vapor pressures of benzene (c 6 h 6) and toluene (c 7 h 8) are p ben = 94.6 torr and p tol = 29.1 torr. 1) raoult's law for a solution of two volatiles is this: Raoult's law plot for a mixture of hexane and heptane. At 373 k, the vapour pressures of the two liquid components (heptane and octane) are 105 kpa and 45 kpa respectively. Raoult's law states that a solvent's partial vapour pressure in a solution (or mixture) is equal or identical to the vapour pressure of the pure solvent multiplied by its mole fraction in the solution.
