12. A sample of sucrose, C12H22011, weighing 0.1265g is burned in a bomb calorimeter. After the reaction is over, it is found that to produce an equal temperature increment electrically, 2082.3 J (calibrated to standard conditions and 298 K) must be consumed. a) Calculate the standard enthalpy of combustion of sucrose at 298 K. b) From the enthalpy of combustion and appropriate data (such as from question 11 above), calculate the standard enthalpy of formation of sucrose at 298 K. c) If the temperature increment in the experiment is 1.743 C, what is the heat capacity (JK-?) of the calorimeter and contents
