Answer:
5.00 moles O₂
General Formulas and Concepts:
Chemistry - Atomic Structure
- Using Dimensional Analysis
- Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
Explanation:
Step 1: Define
3.01 × 10²⁴ molecules O₂
Step 2: Convert
[tex]3.01 \cdot 10^{24} \ mc \ O_2(\frac{1 \ mol \ O_2}{6.022 \cdot 10^{23} \ mc \ O_2} )[/tex] = 4.99834 moles O₂
Step 3: Check
We are given 3 sig figs. Follow sig fig rules and round.
4.99834 moles O₂ ≈ 5.00 moles O₂
