The specific heat of water and steam (water vapor) are 4.18
J/gºC and 2.10 J/gºC respectively. If 127 kJ of heat is need to
heat a 54.0 g sample of water from 74.20 °C to water vapor at
105.50 °C, what is the heat of vaporization of water in J/g?
Assume the boiling point of water is 100.00 °C.
_ J/g
