Table sugar consists primarily of sucrose, C12H22O11(s). The standard enthalpy of combustion for sucrose is the ΔHo for the reaction:

C12H22O11(s) + 12 O2(g) → 12 CO2(g) + 11 H2O(l)
Calculate this ΔHo. Give your answer in units of kJ to five significant figures. Use the following values of ΔHof (in kJ/mol): CO2(g) = –393.51; H2O(l) = –285.83; C12H22O11(s) = –2221.2.
