9. The vapor pressure of liquid ethane thiol, C2H5SH, is 100 mmHg at 260 K. A sample of C2H5SH is placed in a closed, evacuated 557 mL container at a temperature of 260 K. It is found that all of the C2H5SH is in the vapor phase and that the pressure is 69 mm Hg. If the volume of the container is reduced to 213 mL at constant temperature, how many of the following statements are correct? ▪Only ethane thiol vapor will be present ▪Some of the vapor present before reducing the volume will condense ▪Liquid ethane thiol will be present ▪The pressure in the container will be 100 mmHg ▪No condensation will occur (A) 1, (B) 2, (C) 3, (D) 4, (E) 5
