Sucrose (C12H22O11 FW=342.2965) combusts in oxygen to generate carbon dioxide and water vapor. When 20-g sample of it is combusted in a bomb calorimeter with a calorimeter constant of 6.595 kJ/ degrees Celsius, the temperature increases from 25.0 degrees celsius to 72.21 degrees celsius. Determine the heat of combustion (kJ/mol) for sucrose.
