The correct Answer is:
To find the equivalent weight of iron in FeO2, we can follow these steps: ### Step 1: Determine the atomic weight of iron (Fe) The atomic weight of iron (Fe) is approximately 56 g/mol. ### Step 2: Determine the valency of iron in FeO2 In the compound FeO2, iron is in the +4 oxidation state (Fe^4+) because oxygen typically has a -2 oxidation state. Since there are two oxygen atoms, the total negative charge is -4, which means iron must have a +4 charge to balance it. Therefore, the valency of iron in FeO2 is 4. ### Step 3: Calculate the equivalent weight of iron The formula for equivalent weight is given by: \[ \text{Equivalent Weight} = \frac{\text{Atomic Weight}}{\text{Valency}} \] Substituting the values we have: \[ \text{Equivalent Weight of Fe} = \frac{56}{4} \] ### Step 4: Perform the calculation \[ \text{Equivalent Weight of Fe} = 14 \] ### Final Answer The equivalent weight of iron in FeO2 is 14 g/equiv. ---
