enthalpy of combustion of sucrose

When 4.54 g of sucrose is combusted in a constant volume (bomb) calorimeter, 74.9 kJ of heat is liberated. How much energy would be produced if you combusted the sugar in one serving of this cereal (use total sugars as the value)? Wrede, F., and Informatics, NIST / TRC Web Thermo Tables, professional edition (thermophysical and thermochemical data). Previous question … Z. Phys. Go To: Top, Phase change data, Reaction thermochemistry data, IR Spectrum, Mass spectrum (electron ionization), References, Notes. Chem. The change in enthalpy deltaH is then, deltaH = H2 - H2 = {E2 + (PV)2} - {E1 + (PV)1} = deltaE + (PV)2, After combustion, only CO2 is in the gas phase (H2O is liquid). enthalpy of formation = -2221.7 kJ/mol -obtained from "Chemistry - The Molecular Nature of Matter and Change, by Silberberg, Lavieri, and Venkateswaran" ; Boerio-Goates, J., q = (-48.5 kJ / 2.94 g) (4.30 g) = -70.9 kJ, Since volume was constant, PdV = 0 so the mechanical work W done by the gas is zero.
