The vapor pressure of liquid carbontetrachloride, ...

The vapor pressure of liquid carbontetrachloride, CCl4, is100 mm Hg at 296 K.

A sample of CCl4 is placed in a closed,evacuated 574 mL container at a temperature of296 K. It is found that all of theCCl4 is in the vapor phase and that thepressure is 56.0 mm Hg. If the volume of thecontainer is reduced to 371 mL at constanttemperature, which of the following statements are correct?

Choose all that apply.
The pressure in the container will be 100mm Hg.
No condensation will occur.
Only carbon tetrachloride vapor will bepresent.
Liquid carbon tetrachloride will bepresent.
The pressure in the container will be 87.0mm Hg

    Just apply the formula
         P1V1 =P2V2
        (56mmHg/760mmHg * 1.0atm) * 574ml = P2 *371ml
          P2 = 0.114atm = 86.6mmHg
    LAST ONE IS CORRECT
    Hope thishelps!
