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 0.6293 g sample of tridecanedioic acid (C13H2404) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.177x10° g of water. During the combustion the temperature increases from 23.67 to 26.83 °C. The heat capacity of water is 4.184 Jgl•c!. The heat capacity of the calorimeter was determined in a previous experiment to be 888.7 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of tridecanedioic acid based on these data.

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 0.6293 g sample of tridecanedioic acid (C13H,,04) is burned completely in a bomb
calorimeter. The calorimeter is surrounded by 1.177×10' g of water. During the combustion the temperature
increases from 23.67 to 26.83 °C. The heat capacity of water is 4.184 J gl°c!.
The heat capacity of the calorimeter was determined in a previous experiment to be 888.7 J/°C.
Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of tridecanedioic
acid based on these data.
C13H2404(s) + 170,9)-
12 H,O(1) + 13 CO,() + Energy
Molar Heat of Combustion =
kJ/mol
