2C.1 A sample of the sugar D-ribose (C;H1,O5) of mass 0.727 g was placed in a constant-volume bomb calorimeter and then ignited in the presence of excess oxygen. The temperature rose by 0.910 K. In a separate experiment in the same calorimeter, the combustion of 0.825 g of benzoic acid, for which the internal energy of combustion is -3251kJ mol-, gave a temperature rise of 1.940 K. Calculate the enthalpy of formation of D-ribose. 2C.1 A sample of the sugar D-ribose (C;H1,O5) of mass 0.727 g was placed in a constant-volume bomb calorimeter and then ignited in the presence of excess oxygen.
