A 5.4-L closed vessel is filled with 0.46 g of liquid ethanol. This ethanol containing closed vessel
is placed in the freezer and reaches the vapor pressure of 6.65 torr at -11 C.
(i) Is there any liquid ethanol remained in the closed vessel when the container is removed
and warmed to the temperature of 25 C? Justify your answer.
(ii) How many grams of liquid ethanol remained in the vessel at 2.0 C?
The enthalpy changes of vaporization, AH,vap of ethanol is 40.5 kJ/mol.
The molar mass of ethanol is 46.07 g/mol.
