WebThe SI unit of molar heat capacity heat is joule per kelvin per mole (J/(K⋅mol), J/(K mol), J K −1 mol −1, etc.). Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same as joule per degree Celsius per mole (J/(°C⋅mol)). In chemistry, heat amounts are still often measured in ... Web4 de nov. de 2011 · Homework Statement Calculate the heat of reaction per mole of water formed in the acid-base reaction.
