1. The vapor pressure of liquid pentane, C5H12, is 100. mm Hg at 260 K. A 0.185 g sample of liquid C5H12 is placed in a closed, evacuated 310. mL container at a temperature of 260 K.
Assuming that the temperature remains constant, will all of the liquid evaporate? _____ (yes/no)
What will the pressure in the container be when equilibrium is reached?___ mm Hgâ
2. The vapor pressure of liquid butanol, C4H9OH, is 100. mm Hg at 343 K.
A sample of C4H9OH is placed in a closed, evacuated 549 mL container at a temperature of 343 K. It is found that all of the C4H9OH is in the vapor phase and that the pressure is 57.0 mm Hg. If the volume of the container is reduced to 368 mL at constant temperature, which of the following statements are correct?
Choose all that apply.
A. Liquid butanol will be present.
B. No condensation will occur.
C. Only butanol vapor will be present.
D. The pressure in the container will be 100. mm Hg.
E. Some of the vapor initially present will condense.
