Need help with this equation! Can anybody lay out an answer please?


Use this equation; 4Fe + 3O2 -> 2Fe2O3.

If 96.0 grams of oxygen react, what mass of iron was oxidized?


A.) 32.0 g

B.) 96.0 g

C.) 167 g

D.) 223 g


Thanks!

As you can see in the reaction, for each \(3O_2\) that reacts, two \(Fe_2O_3\) are created.

There are \(\frac{96.0}{16}=6mol\) of oxygens reacting, hence \(2*6/3=4\) mols of iron will be oxidized, which represents \(24*55.8=\boxed{223g}\)
