Aluminum Oxide Can Be Reduced to Aluminum Metal Using Carbon $\Delta$

Aluminum oxide can be reduced to aluminum metal using carbon, the other reaction product being carbon monoxide. Determine the enthalpy change when 12.5 g of aluminum is produced by this method.[ $\Delta$ H°_f(carbon monoxide) = -110.5 kJ/mol; $\Delta$ H°_f(aluminum oxide) = -1669.8 kJ/mol]

A) 725 kJ
B) 697 kJ
C) 310 kJ
D) 361 kJ
E) 1504 kJ
