Recall that the oxidation number of oxygen (O) in most compounds is typically -2.
Let the oxidation number of iron (Fe) be represented as x.
Write the equation based on the fact that the sum of oxidation numbers in a neutral compound is zero: \(2x + 3(-2) = 0\).
Simplify the equation: \(2x - 6 = 0\).
Solve for x to find the oxidation number of Fe: \(2x = 6\) which gives \(x = +3\).
