Acetaldehyde - NIST
WebThe standard heat of formation of liquid ethanol, ΔH f ° (C 2 H 6 O, l), is -277.6 kJ/mol. The heat of combustion of ethanol, ΔHc° (C2H6O, l) = 2*393.51 + 6*142.915 + (-277.6) = 1366.91 kJ/mol. This can be converted to kJ per mass units: The molweight of ethanol is (2*12.01 + 6*1.01 + 1*16.00) = 46.08 g/mol WebAug 2, 2024 · Calculate the specific heat of cadmium.
