Questions 14-17 refer to the following information.

Substance | Lewis Diagram | Boiling Point
CH₃OH | [VISUAL] | 338 K
C₂H₅OH | [VISUAL] | 351 K

Equimolar samples of CH₃OH(l) and C₂H₅OH(l) are placed in separate, previously evacuated, rigid 2.0 L vessels. Each vessel is attached to a pressure gauge, and the temperatures are kept at 300 K. In both vessels, liquid is observed to remain present at the bottom of the container at all times. The change in pressure inside the vessel containing CH₃OH(l) is shown below.

1. The temperature of the CH₃OH is increased from 300 K to 400 K to vaporize all the liquid, which increases the pressure in the vessel to 0.30 atm. The experiment is repeated under identical conditions but this time using half the mass of CH₃OH that was used originally. What will be the pressure in the vessel at 400 K ?
