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.

  • Chemistry -

    Use Psoln = XsolventPsolvento

    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.
