Hess law states that enthalpy of the reaction is equal enthalpy of products minus enthalpy of reagents.

joyabraham:
Thank you for the advice. Enthalpy of Al(OH)3 is not found in any site in internet. If anybody has the answer to my question for this reaction AlF3 (l) + 3H2O (g)→ Al(OH)3 (l) + 3HF (g) kindly give. Whatever guidance provided by earlier replies did not help.

Googling for "Aluminum hydroxide enthalpy of formation" got me the answer in no time.

joyabraham:
Does anybody know if this is an exothermic or endothermic reaction?

Orcio_87:
True, but joyabraham asks for a liquid (melted) AlF3 and Al(OH)3, so this requires additional data to find (heat capacities and enthalpies of melting).
