Use the References to access important values if needed for this question.
The following information is given for benzene, C,H6, at 1 atm:
boiling point = 80.1 °C
AHvap(80.1 °C) = 30.7 kJ/mol
melting point = 5.50 °C
AHfus(5.50 °C) = 9.95 kJ/mol
specific heat liquid = 1.74 J/g°C
At a pressure of 1 atm,
kJ of heat are needed to vaporize a 38.7 g sample of liquid benzene at its normal boiling point
of 80.1 °C.
