____8.A 0.900-g sample of toluene, C 7 H 8 , was completely burned in a bomb calorimeter containing 4560. g of water whichincreased in temperature from 23.800°C to 25.718°C. What is ∆ E for the reaction in kJ/mol C 7 H 8 ? The heat capacity of the calorimeter was 780. J/°C. The specific heat of water is 4.184 J/g•°C.
