A chemical equation is shown below.

4Fe + 3O2
⟶2Fe2O3

The mass of 2Fe2O3 produced must be equal to

A chemical equation is shown below.

4Fe + 3O2
⟶2Fe2O3

The mass of 2Fe2O3 produced must be equal to

the mass of 4Fe less the mass of 3O2.

the total mass of 4Fe and 3O2.

twice the total mass of 4Fe and 3O2.

one-half the mass of 4Fe and 3O2.

The mass of 2Fe2O3 produced in the chemical reaction is equal to the total mass of 4Fe and 3O2. Therefore, the correct answer is the total mass of 4Fe and 3O2.
