Question 4 A sample of 3.15 moles of a substance was burned in a constant pressure calorimeter. The temperature of the calorimeter increased from 24.5 °C to 55.4 °C. The heat capacity of the calorimeter is 10.33 kJ/K. AT: (55.4-24.5) Calculate the enthalpy of combustion, AHO comb' q= CAT of the substance in kJ/mol. 1 pts Give your answer in kJ/mol to ONE decimal place. Do NOT include units in your answer. If your answer is negative, use a hyphen "-", followed directly by the number. Do NOT use an underscore "_" or include any extra spaces. For example, if your answer is -14.943 kJ/mol, input -14.9
