the combustion of 1.900g of glucose C6H12O6 in a bomb calorimeter with a heat capacity of 5.0kJ/C results in an increase in the temperature of the calorimeter and its contents from 22.79 degrees Celsius to 28.71 degrees Celsius. What is internal energy change for the combustion of the 1.900 g of glucose? Calculate the enthalpy of combusion in kJ/mol
