WebMar 7, 2016 · Explanation: So the smallest molar quantity is that of oxgen, C = 0.0130 ⋅ mol 0.0065 ⋅ mol; H = 0.0390 ⋅ mol 0.0065 ⋅ mol; O = 0.0065 ⋅ mol 0.0065 ⋅ mol. So CnH mOp = C2H 6O. So that's the empirical formula, the simplest whole number ratio that defines constituent atoms in a species. WebFor some compounds, Calvet microcalorimetry was used for the determination of standard molar enthalpies of sublimation, at T = 298.15 K. Through combination of the combustion and sublimation results, the standard molar enthalpies of formation in the gas phase, at T = 298.15 K, were derived and used to infer about gas phase energetics.
