4. A 1.00-g sample of octane (C3H18) was burned in a bomb calorimeter with 1300 g of water (H20). The temperature increase from 25°C to 34.10°C. Calculate the heat of combustion of octane in kJ/mol if the heat capacity of the calorimeter is 890 J/°C, and the specific heat of water is 4.184 J/g°C. Solution A. Calculate the heat absorbed by the water, QH20 B. Calculate the heat absorbed by the calorimeter, Qcal C. Determine the total heat absorbed by the water and the calorimeter.
