\(0.3 g\) of ethane undergoes combustion at \(27^{\circ} C\) in a bomb calorimeter. The temperature of calorimeter system (including the water) is found to rise by \(0.5^{\circ} C\). The heat evolved during combustion of ethane at constant pressure is -____\(kJ mol ^{-1}\). (Nearest integer)
[Given: The heat capacity of the calorimeter system is \(20 kJ K ^{-1}, R =8.3 JK ^{-1} mol ^{-1}\).
Assume ideal gas behaviour.
Atomic mass of \(C\) and \(H\) are 12 and \(1 g mol ^{-1}\) respectively]
