Consider the reaction:
C12H22O11(s) + 12 O2(g)→12 CO2(g) + 11 H2O(l)
in which 10.0 g sucrose, C12H22O11, was burned in a bomb calorimeter with a heat capacity of 7.50 kJ/°C. The temperature increase inside the calorimeter was found to be 22 °C. Calculate the change in interneal energy, ΔE, for this reaction per mole of sucrose.
Express the change in internal energy in kilojoules per mole to three significant figures.
