WebFor example, the bond enthalpy for a carbon-carbon single bond is about 348 kilojoules per mole. You might see a different value, if you look in a different textbook. However, we're … WebThe specific heat capacity can be calculated from the molar heat capacity, and vise versa: c p = C p / M and . C p = c p. M. where. c p = specific heat capacity. C p = molar heat capacity. M = molar weight of the actual substance (g/mol). Example: Methanol (with molecular formula CH3OH) has a molar heat capacity, C p, of 81.1 J/(mol K).
