Asample of octane (c8h18 that has a mass of 0.750 g is burned in a bomb calorimeter. as a result, the temperature of the calorimeter increases from 21.0°c to 41.0°c. the specific heat of the calorimeter is 1.50 j/(g °c, and its mass is 1.00 kg. how much heat is released during the combustion of this sample? use .

30 kJ is released during the combustion of this sample.

Explanation:

Heat released during combustion = Heat gained by calorimeter

Mass of calorimeter= m = 1.00 kg=1000 g

Change in temperature of the calorimeter = ΔT = 41.0 °C - 21.0 °C =20.0 °C

Specific heat if calorimeter = c = 1.50 J/g °C

Heat released during combustion = Q

30 kJ is released during the combustion of this sample.
