A student leaving campus for spring break wants to make sure the air in his dorm room has a high water vapor pressure so that his plants are comfortable. The dorm room measures 3.45 m  4.64 m  3.63 m and the student places a pan containing 0.671 L of water in the room. Assume that the room is airtight, that there is no water vapor in the air when he closes the door, and that the temperature remains a constant 22 C. The vapor pressure of water at 22 C is 19.8 mm Hg. 

(a) Calculate the pressure that the water vapor would exert if all of the liquid water evaporated. _______ mm Hg 

(b) Will all of the water in the pan evaporate?
