5.86 kJ/C x (29.4-25.8) = q
q/0.514 x (molar mass biphenyl/mol) = ?
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 provided is -6330 kj/mol.
I'm looking for help with the solution.
