In a factory in which metal parts are degreased with organicsolvents, the intern breaks a bottle containing a mixture of 5liters of tetrachloroethylene (PER, MW = 166 g/mol, Ï = 1.62 g/cm3, Pv = 18 mm Hg) and 10 liters of trichloroethene (TCE, MW = 131g/mol, Ï = 1.46 g/cm3 , Pv = 54 mm Hg) in a closed room at 20oC.The room has a total volume of 50 m3 . Assume PER and TCE form anideal mixture in the liquid phase.
a. What is the composition (in mole fractions) of the liquidmixture in the bottle?
b. What are the equilibrium concentrations of PER and TCE in theair of the room in mg/L? Note: Make sure to use Raoult’s Law. [PER]= 49.9 mg/L
c. What is the composition (in mole fractions) of the remainingliquid on the floor after equilibrium? XPER = 0.790
