The complete combustion of salicylic acid releases 21.90 kJ of
energy per gram of salicylic acid. In a particular bomb calorimeter
(initially at room temperature), the combustion of 0.2038 g of
salicylic acid, in the presence of excess oxygen, causes the
temperature of the calorimeter to rise by 2.94 °C. When a 0.2172-g
sample of an unknown organic substance is similarly burned in the
same calorimeter, the temperature rises by 4.58 °C. What is the
energy of combustion per unit mass of the unknown
substance?
