Explanation:

Step 1: Define

6.022 × 10²² atoms Fe (iron)

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

  1. Set up:                    [tex]\displaystyle 6.022 \cdot 10^{22} \ atoms \ Fe(\frac{1 \ mol \ Fe}{6.022 \cdot 10^{23} \ atoms \ Fe})[/tex]
  2. Divide:                    [tex]\displaystyle 0.1 \ mol \ Fe[/tex]
