Explanation / Answer

Now first for (Mgcl2*6H2O)

Date from perry is Heat of formation H(Mgcl2*6H2O)= –2500 kJ /mol

                           Heat of formation H(Mgcl2)= –642 kJ /mol

                           Heat of formation H(H2O)= –286 kJ /mol

                  

MgCl2(s)+ 6H2O(l)MgCl2.6H2O(s)

H=Hproducts– Hreactants

     =–2500 – (–642) + 6(–286)1

H=–142 kJ/mol

     Heat of Solution of (Mgcl2*6H2O) =–142 kJ/mol

In this way Heat of Solution of (BaCl2*2H2O) = 8.8 kJ/mol

and            Heat of Solution of (Srcl2*6H2o) = -31.39 kJ/mol
