A Bomb Calorimeter Has a Heat Capacity of 2

A bomb calorimeter has a heat capacity of 2.10 kJ/K. When a 0.196 g sample of gas with a molar mass of 28.0 g/mol was burned in this calorimeter, the temperature increased by 2.15 K. Calculate the energy of combustion for 1 mol of this gas.

A) -4.52 kJ
B) -0.0316 kJ
C) -6.45 × 10² kJ
D) -1.26 × 10² kJ
E) -2.30 × 10¹ kJ
