A Bomb Calorimeter Has a Heat Capacity of 2 $\times$ 10³ KJ/mol

A bomb calorimeter has a heat capacity of 2.47 kJ/K.When a 0.109-g sample of ethylene (C₂H₄) was burned in this calorimeter,the temperature increased by 2.22 K.Calculate the energy of combustion for one mole of ethylene.

A) -5.29 kJ/mol
B) -50.3 kJ/mol
C) -636 kJ/mol
D) -0.269 kJ/mol
E) -1.41 $\times$ 10³ kJ/mol
