A 0.54 g sample of fructose (MW = 180. g/mol) is burned in a bomb calorimeter that has a heat capacity of 2.69 kJ/oC. The temperature of the calorimeter increases by 3.16oC. Calculate the molar heat of combustion of fructose using the data from this experiment. Since this experiment is carried out under conditions of constant volume, we are measuring ∆E. Your answer should be in kJ/mol and entered to 3 sig. fig. ∆E=?
