Explanation / Answer

use,
(delta G)rxn = (delta G)(H2O) + 2*(delta G)(LiCl) - {(delta G)(Li2O) + 2(delta G)(HCl)}
-244.88 = -228.6 + 2*(-384.0) - {(delta G)(Li2O) + 2*(-95.27)}
-244.88 = -228.6 - 768 - (delta G)(Li2O) + 190.5
-244.88 = -806.1 - (delta G)(Li2O)
(delta G)(Li2O) = -561.22 KJ/mol

Answer : -561.22 KJ/mol
