In the balanced chemical equation:

\[ 4Fe + 3O_2 \rightarrow 2Fe_2O_3 \]

The product is \( 2Fe_2O_3 \). Each formula \( Fe_2O_3 \) contains 3 oxygen atoms. Since there are 2 formula units of \( Fe_2O_3 \), you can calculate the total number of oxygen atoms as follows:

\[ 2 \, \text{units} \times 3 \, \text{oxygen atoms/unit} = 6 \, \text{oxygen atoms} \]

Therefore, the total number of oxygen atoms present in the products of this reaction is **6**.
