On a particular summer day, the temperature is 30.0°C and the relative humidity is 80.0% (which means that the partial pressure of water vapor in the ambient air is 80.0% of the equilibrium vapor pressure of water). A sample of this air is placed in a 1.00-L flask, which is then closed and cooled to 5.0°C. What is the mass (in grams) of water that still exists as vapor in the flask? How much liquid water (in grams) condenses out?
