<h3>Explanation:</h3>

<u>Step 1: Define</u>

2.25 mol Fe

<u>Step 2: Identify Conversions</u>

Molar Mass of Fe - 55.85 g/mol

<u>Step 3: Convert</u>

Set up: $\displaystyle 2.25 \ mol \ Fe(\frac{55.85 \ g \ Fe}{1 \ mol \ Fe})$
Multiply: $\displaystyle 125.663 \ g \ Fe$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

125.663 g Fe ≈ 126 g Fe
