Answer:

13.8 mol CO₂

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

8.32 × 10²⁴ molecules CO₂

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

[tex]8.32 \cdot 10^{24} \ molecules \ CO_2(\frac{1 \ mol \ CO_2}{6.022 \cdot 10^{23} \ molecules \ CO_2} )[/tex] = 13.816 mol CO₂

Step 4: Check

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

13.816 mol CO₂ ≈ 13.8 mol CO₂
