Biphenyl (C1 2H1 0) burned in a bomb calorimeter in

order to determine its heat of combustion. The heat
capacity of the calorimeter was 5.86 kJ/°C When
0.514 g of biphenyl was burned, the temperature of
the calorimeter increased from 25.8 °C to 29.4 °C.
Determine the enthalpy of combustion for biphenyl.

the correct answer is -6330 kj/mol
