How much energy must be removed from a 125 g sample of benzene (molar mass= 78.11 g/mol) at 425.0 K to liquify the sample and lower the temperature to 335.0 K? AHvap = 33.9 kJ/mol AHfus = 9.8 kJ/mol Cliq= =1.73 J/g °C Cgas = 1.06 J/g°C Csol = 1.51 J/g°C Tmelting =279.0 K Tboiling = 353.0 K A) 38.9 kJ B) 95.4 kJ C) 67.7 kJ D) 54.3 kJ E) 74.4 kJ
