A 114g sample of sucrose undergoes incomplete combustion according to the reaction

C12H22011 + 5O2 ---> 4C + 6CO + 2CO2 + 11H2O

using the chart of enthalpies of formation determine the enthalpy released by the sample


i think that it is a simple enthalpy problem but in the chart of enthalpies the enthalpy of C12H22O11 is not given, so how am i supposed to answer the question?! thanks for any help!
