The combustion of 1.013 g of vanillin,
C8H8O3, in a bomb calorimeter
which has a heat capacity as 4.90 kJ/oC, causes the
temperature to rise from 24.89 oC to
30.09 oC. What is the heat of combustion of
vanillin, expressed in kilojoules per mole of
C8H8O3? (C = 12.0 g/mol; H = 1.0
g/mol; O = 16.0 g/mol)
