1. A quantity of 4.275 g of an organic compound with a molecular formula C₁2H₂2 was burned in a constant volume bomb calorimeter. The temperature of the water rose from 20.50 °C to 37.50°C. If the quantity of water surrounding the calorimeter was exactly 2255 g and the heat capacity of the bomb calorimeter was 1.150kJ/°C, calculate the molar heat of combustion in kJ/mol of C₁2H22.

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 0.8608 g sample of glutaric acid (C3HgO4) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.029x103 g of water. During the combustion the temperature increases from 25.01 to 27.84 °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 839.5 J°C.
