CHEMISTRY QUESTION !!!!!!!?

Ethanol, C_2 H_5 OH, boils at 78.29 degrees C. How much energy, in joules, is required to raise the temperature of 1.00kg of ethanol from 20.0 degrees C to the boiling point and then to change the liquid to vapor at that temperature? (The specific heat capacity of liquid ethanol is 2.44 j/g K, and its enthalpy of vaporization is 855 j/6.)
