A chemist mixes 100ml of H2O at 30 degrees Celsius and 56.0g of CaOin a calorimeter.
The following reaction occurs"
CaO(s) +H2O(l)--->Ca(OH)2(s) ΔH= -16.0 kcal/mol

The heat capacity Ca(OH)2(s) is 19.2 cal/mol*degreeCelsius and the heat of vaporization of water is 540 cal/g. How much liquid water and how much steam would result?
