CHM 2046C Module 7II Chapter 13 Sample Exam

Part V: Vapor Pressure Calculation 5 points

If 0.50 g of pure water is sealed in an evacuated 5.0 L flask and the whole assembly is heated to 60^oC, will the pressure be equal to or less than the equilibrium vapor pressure at this temperature? If less what will be the pressure in the flask? What if you used 2.0 g of water? Under either set of conditions, is any liquid water left in the flask, or does all the water evaporate? (The equilibrium vapor pressure of water at 60^oC is 149.4 torr)
