Given the following information for ethanol (C2H5OH) :

c(s) = 4.460 J/(mol × °C)
c(l) = 105.8 J/(mol × °C)
c(g) = 78.28 J/(mol × °C)
melting point = –114°C
boiling point = 78.0°C
ΔHfus = 5.020 x 103 J/mol
ΔHvap = 3.856 x 104 J/mol

How much heat is absorbed when raising the temperature of a 0.2720 mole sample of ethanol from 60.00°C to 90.00°C?
