Using Dimensional Analysis

<h3>Explanation:</h3>

Step 1: Define

3.01 × 10²⁴ atoms O₂

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

Set up: $\displaystyle 3.01 \cdot 10^{24} \ atoms \ O_2(\frac{1 \ mol \ O_2}{6.022 \cdot 10^{23} \ atoms \ O_2})$
Multiply/Divide: $\displaystyle 4.99834 \ mol \ O_2$

Step 4: Check

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

4.99834 mol O₂ ≈ 5.00 mol O₂
