A sample of the sugar D-ribose (C5H10O5) of mass 0.727g was placed in a constant volume calorimeter and then ignited in the prescence of excess oxygen. The temperature rose by 0.910K In a separate experiment in the same calorimeter, the combustion of 0.825g of benzoic acid for which the internal energy of combustion is -3251 KJmol-1 gave a temperature rise of 1.940K. Calculate the internal energy of combustion of D-ribose and its enthalpy of formation.
