Question

Ac sample of octane that has a mass of 0.750 g is burned in a bone calorimeter. As a result, the temperature if the calorimeter increases from 21.0 °C to 41°C . The specific heatv of the calorimeter is 1.50 J/(g*°C), and it's nass is 1.0 kg. How much heat is released during the combustion

Answer 1

From the specific heat of the calorimete which is 1.50 J/(g*°C), and it's mass is 1.0 kg, then the amount of energy that is released during the combustion is 30.0 kJ.

Answer 2

How much heat is released during the combustion?

30.0 kJ

Hope this helps.
