Ethanol (C2H5OH) boils at a temperature of 78.3oC.

What amount of energy, in joules, is necessary to heat to boiling and then completely vaporize a 22.8 g sample of ethanol initially at a temperature of 16.5oC.

The specific heat of ethanol is approximately constant at 2.44 JK-1g-1
The heat of vaporization of ethanol is 38.56 kJ mol-1.
