A 6.55 g sample of aniline (C6H5NH2, molar mass = 93.13 g/mol) was combusted in a bomb calorimeter. If the temperature rose by 32.9C, use the information below to determine the heat capacity of the calorimeter.
 
  4 C6H5NH2(l) + 35 O2(g)  24 CO2(g) + 14 H2O(g) + 4 NO2(g)
 
   Hrxn= -1.28  104 kJ
 
  A) 97.3 kJ/C
  B) 38.9 kJ/C
  C) 5.94 kJ/C
  D) 6.84 kJ/C
  E) 12.8 kJ/C
