Iron oxide has formula `Fe_(0.94)O`. What fraction of Fe exists as `Fe^(+3)` ?

Explanation

To find the fraction of Fe that exists as Fe^(+3) in the iron oxide formula Fe_(0.94)O, we can follow these steps:

### Step 1: Define Variables
Let:
- \( x \) = amount of Fe in the +3 oxidation state (Fe^(+3))
- \( 0.94 - x \) = amount of Fe in the +2 oxidation state (Fe^(+2))

### Step 2: Determine the Charge Balance
