The combustion of 1.663 g of fructose, C,H,0,(s), in a bomb calorimeter with a heat capacity of 5.50 kJ/°C results in an
increase in the temperature of the calorimeter and its contents from 22.68 °C to 27.40 °C. What is the internal energy change,
AU, for the combustion of 1.663 g of fructose?
AU =
13.87
kJ
Incorrect
Calculate the enthalpy of combustion, AHc, of fructose in kilojoules per mole.
AH. =
-2810.13
kJ/mol
