Vapour pressure is NOT impacted by volume! In a container, the liquid and vapor are in balance. Some of the vapor in the container changes from a vapor state to a liquid state when the volume is altered, for example, lowered. Additionally, part of the liquid will turn into its vapor state when the volume is raised.

Answer is 17.54 mmHg

Answer is 17.54 mmHg
