You need to know the molar mass M ( g / m o l) of the material (substance). Say the Enthalpy in J / g is H w, then the Enthalpy in J / m o l is H M, with: H M = H w × M. Divide by 1000 to convert to k J / m o l. If the material is not a pure substance (i.e. a mixture) then you need to calculate a molar average for M of the material.
