Vanillin is a natural constituent of vanilla that is also manufactured for use in artificial vanilla flavoring. The combustion of 1.013 g of vanillin, C3H3O3, in a bomb calorimeter that has a heat capacity of 4.90 kJ °C-1 causes the temperature to rise from 24.89°C to 30.09°C. What is the heat of combustion of vanillin in terms of kcal per gram?
