At 25 °C, water has an equilibrium vapor pressure of 23.8 mm Hg. If 2.500 g of water is sealed in an evacuated 10.0-L flask and heated to 25 °C, what mass of water will evaporate? Assume any liquid remaining in the flask has a negligible volume tube with 3 gas chambers: 1st gas chamber: P = 1.00 atm, 5.00 L 2nd gas chamber: P = 2.00 atm, 3.00 L 3rd gas chamber: P = 3.00 atm, 2.00 L
