A hydrocarbon sample was burned in a bomb calorimeter. The temperature of the calorimeter and the 1.00 kg of water rose from 20.45 celsius to 23.65 celsius.The heat capacity of the caloimeter, excluding the water, is 2.21 kJ/degree celsius. using this information, determine the heat released by the combustion.
I have no idea how to do this. Please explain steps so I can see how to do it for myself

    The heat released is the total of the heat required to raise the temperature of the water (1,000 grams) + heat to raise the temperature of the calorimeter.

    q = [mass H2O x specific heat water x (Tfinal-Tinitial)] + [cal x (Tfinal-Tinitial)]] = 0
    Solve for q.
