How do i solve this problem?

Ethanol boils at a temperature of 78.29oC. What amount of energy, in joules, is necessary to heat to boiling and then completely vaporize a 16.5 gram sample of ethanol initially at 18oC? The ΔHvap is 38.56kJ/mol and the specific heat of ethanol(l) is approximately constant at 2.44 J/gK. The formula for ethanol is C2H5OH
