Aluminum metal is exposed to atmospheric oxygen, it is oxidized to form aluminum oxide. How much heat is released by the complete oxidation of 24.2 grams of aluminium at 25°C and 1atm.

You need to look up the heat of formation of Al2O3 (H<sup>o</sup>f). I'm sure you have a set of tables in your text in kJ/mol.
Then ?kJ/mol x # mol in the equation x (24.2/atomic mass Al) = ?
