A 6.55 g sample of C6H5NH2 was combusted in a bomb caloriemeter. If the temp rose by 32.9 degreese C use the info below to determine the heat capacity of the calorimeter (Ccal)
C6H5NH2 = 93.13 g/mol, O2 = 32.00 g/mol CO2 = 44.01 g/mol H20 = 18.02 g/mol NO2 = 46.01 g/mol
4 C6H5NH2 + 35 O2 → 24 CO2 = 14 H20 = 4 NO2
