To analyze why FeO has a non-stoichiometric composition with the formula Fe₀.₉₅O₁.₀₀, we need to understand the concept of non-stoichiometry and the defects that can occur in solid-state compounds. ### Step-by-Step Solution: 1. **Understanding Non-Stoichiometry**: - Non-stoichiometric compounds do not have a fixed ratio of their constituent elements. In this case, FeO is expected to have a 1:1 ratio of iron (Fe) to oxygen (O), but the analysis shows it has a composition of Fe₀.₉₅O₁.₀₀. 2. **Identifying the Type of Defect**: ...
