The standard molar enthalpy of formation of sucrose (C12H22O11) is -2222 kJ/mol. What is the enthalpy of combustion of a sugar cube of sucrose weighing 2 g?
If 25% of this energy can be converted to work by the human body, to what height can a 100 kg man climb on the energy derived from such a sugar cube? Assume the man is on the surface of the Earth.
