• Using Dimensional Analysis

Step-by-step explanation:

Step 1: Define

6.27 × 10¹⁹ atoms

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

1. Set up:
   `\displaystyle 6.27 \cdot 10^(19) \ atoms((1 \ mol)/(6.022 \cdot 10^(23) \ atoms))`
2. Multiply/Divide:
   `\displaystyle 0.000104 \ mol`

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

Since our final answer already has 3 sig figs, there is no need to round.
