Cаlculаte the аmоunt оf energy (in kJ) tо be required for a 100-g sample of benzene (C6H6, M = 78.115 g/mol) at 2.00 °C to rise to 80.00 °C? The normal freezing point for benzene is 5.85 °C and boiling point is 80.10 °C. Physical data associated with benzene is given below but not all of the data may be needed. Give the answer in kJ and at least one decimal place. Cs, solid = 1.51 J/g·°C Cs, liquid = 1.73 J/g·°C Cs, gas = 1.06 J/g·°C ΔHfus = 9.80 kJ/mol ΔHvap = 33.9 kJ/mol
