Use the data in the table to calculate the Delta G0 of the following reaction at 298k:
Al2O3 > Delta G fusion 1582.3
HCl> 131.2
AlCl3 628.8
H2O  237.1
The equation is Al2O3 + 6HCl > 2 AlCl3 + 3H2O
products  reactants?
[2(628.8)+3(237.1)  (1582.3)+6(131.2) =1178.8 KJ
But the answer is supposed to be +400.6 KJ/mol

If you do the math right you get 400.6 kJ/mol. At least that's what I obtained.
