What is the relation between Molar enthalpy and Change in enthalpy? How do we use them together?

If I calculate Q=mc(delta t) as Q= (54.25 g)(4.19 J/g C)( 6 C) and get 1363.845 J. How do I convert this into change in enthalpy and molar enthalpy? This was done for a Calorimetry assignment.


CaCl2 mass = 5.50 g

Water mass initial = 50.00 g

Solution mass final (water) = 54.25 g

Molar Mass CaCl2 = 110.98 g/mol

Initial temperature = 25.0 C

Final temperature = 31.0 C
