Use the References to access important values if needed for this question. A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.3163 g sample of azulene (C1₁0Hg) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.061x10³ g of water. During the combustion the temperature increases from 23.18 to 25.79 °C. The heat capacity of water is 4.184 J g-¹°C-1. MindTap - Cenga X References The heat capacity of the calorimeter was determined in a previous experiment to be 797.7 J/°C. Molar Heat of Combustion = Submit Answer Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of azulene based on these data.
