10. A bomb calorimeter assembly containing 983.5 g of water (4.184 J/g.°C) is calibrated by the combustion of 1.354-g anthracene (C₁4H10; AcH°298K = -7067 kJ/mol). The temperature of the calorimeter rises from 24.87 °C to 35.63°C. When 1.053 g of citric acid is burned in the same assembly, but containing 968.6 g of water, the temperature increases from 25.01 °C to 27.19 °C. What is the heat of combustion of citric acid, C6H³O7, expressed in kilojoules per mole? [-1.95×10³ kJ/mol]
