From the given information, what is the standard
P enthalpy of formation for \( \mathrm{Al}_{2} \mathrm{O}_{3}(\mathrm{~s}) \) ?

W \( 2 \mathrm{Al}_{2} \mathrm{O}_{3}(\mathrm{~s}) \rightarrow 4 \mathrm{Al}(\mathrm{s})+3 \mathrm{O}_{2}(\mathrm{~g}) ; \Delta \mathrm{H}^{\circ} \) rxn \( =3352 \mathrm{~kJ} \)
(1) \( -6704 \mathrm{~kJ} / \mathrm{mol} \)
(2) \( -3352 \mathrm{~kJ} / \mathrm{mol} \)
(3) \( -1676 \mathrm{~kJ} / \mathrm{mol} \)
(4) \( 1676 \mathrm{~kJ} / \mathrm{mol} \)
