question 50

Multiple Choice

When 1.365 g of anthracene,C₁₄H₁₀,is combusted in a bomb calorimeter that has a water jacket containing 500.0 g of water,the temperature of the water increases by 25.89°C.Assuming that the specific heat of water is 4.18 J/(g ∙ °C) ,and that the heat absorption by the calorimeter is negligible,estimate the enthalpy of combustion per mole of anthracene.
