0.3g of ethane undergoes combustion at 27∘C in a bomb calorimeter. The temperature of calorimeter system (including the water) is found to rise by 0.5∘C. The heat evolved during combustion of ethane at constant pressure is _______ kJ‌mol‌‌−1.
(Nearest integer)
[Given: The heat capacity of the calorimeter system is 20‌kJ‌K−1,R=8.3JK−1mol−1.
Assume ideal gas behaviour.
Atomic mass of C and H are 12 and 1gmol−1 respectively]
