#2Fe(s) + 3/2O_2(g) rarr Fe_2O_3(s)#

Explanation:

We need a stoichiometric equation:

#2Fe(s) + 3/2O_2(g) rarr Fe_2O_3(s)#

And thus if #12.0*mol# of metal oxidize, then CLEARLY, by the given stoichiometry, #18.0*mol# of dioxygen gas are required.

What masses of gas and metal are required for the given reaction?
