Question

Butanone, CH3CH2COCH3, has a vapor pressure of 100. Torr at 25°C; at the same temperature, propanone, CH3COCH3, has a vapor pressure of 222 Torr. What mass of propanone must be mixed with 322.0 g of butanone to give a solution with a vapor pressure of 135 Torr? Assume ideal behavior.
Use P<sub>soln</sub> = X<sub>solvent</sub>P<sub>solvent</sub><sup>o</sup>

That will calculate X for each solvent.
Go from there to grams of each (one is given in grams). Post your work if you get stuck.
