|                 |         | (g/mol)        | (mol)         | (g)                                        |

### Explanation
This table is designed to assist you in determining the molar mass of iron(II) oxide (FeO) by breaking down its composition into its cation (Fe²⁺) and anion (O²⁻) parts. For each part:
1. **Formula**: Indicates the chemical formula of the ion.
2. **Molar Mass of Ion**: The mass of one mole of the respective ion in grams per mole (g/mol).
3. **Number of Ions**: Represents the number of each type of ion in one formula unit of iron(II) oxide.
4. **Mass of Ion in One Mole of Iron(II) Oxide**: The product of the molar mass of the ion and the number of ions, giving the total mass contribution of that ion to the compound.

Fill out the respective molar masses, calculate the contributions of each ion, and sum them to get the total molar mass of iron(II) oxide.
