Final answer:
If we have 1.10 moles of FeO, which has a one-to-one molar ratio of Fe to FeO, we therefore have 1.10 moles of iron.
Step-by-step explanation:
When determining how many moles of iron are there in 1.10 moles of FeO, you need to consider the stoichiometry of the compound. Iron (II) oxide, or FeO, consists of one iron atom (Fe) and one oxygen atom (O). Since there is a one-to-one molar ratio between Fe and FeO in the compound, each mole of FeO will contain one mole of iron.
Therefore, if you have 1.10 moles of FeO, this means you also have 1.10 moles of iron, as the stoichiometric mole ratio in the chemical formula indicates a direct correlation between the moles of FeO and the moles of Fe present.
Example Calculation:
If the formula of iron oxide is FeO, then for each mole of FeO, you will always have one mole of Fe. So, in this case:
- 1.10 moles of FeO × 1 mole of Fe per mole of FeO = 1.10 moles of Fe.
