A 6.55 g sample of aniline (C6H5NH2, molar mass = 93.13 g
) was combusted in a bomb calorimeter. If the temperature rose by 32.9 °C, use the information below to determine the heat capacity of the calorimeter. 4C6H5NH2(l) + 35O2(g) → 24CO2(g) + 14H2O(g) + 4NO2(g)

A) 97.3 kJ 
B) 38.9 kJ 
C) 5.94 kJ 
D) 6.84 kJ 
E) 12.8 kJ
