Question

When a 3.08 g sample of liquid octane (C8H18) is burned in a bomb calorimeter, the temperature of the calorimeter rises by 26.9 °C. The heat capacity of the calorimeter, measured in a separate experiment, is 6.22 kJ/°C. The calorimeter also contains 3.00 kg of water, with a specific heat capacity of 4.18 J/g°C. Determine the heat of combustion of octane in units of kJ/mol octane.

Step 1

Calculate the total heat capacity of the calorimeter and water. The heat capacity of the calorimeter is given as 6.22 kJ/°C. The heat capacity of the water can be calculated using the formula: Heat capacity of water = mass of water × specific heat capacity of Show more…
