On a particular summer day, the temperature is 30.0C 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 5.0C. What is the mass (in grams) of water that still exists as vapor in the flask? How much liquid water (in grams) condenses out?
