Step-by-step explanation:

Step 1: Define

9.24 × 10²³ molecules CO₂

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

1. Set up:
   `\displaystyle 9.24 \cdot 10^(23) \ molecules \ CO_2((1 \ mol \ CO_2)/(6.022 \cdot 10^(23) \ molecules \ CO_2))`
2. Multiply/Divide:
   `\displaystyle 1.53437 \ mol \ CO_2`

Step 4: Check

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

1.53437 mol CO₂ ≈ 1.53 mol CO₂
