Answer:
Explanation:
All of above except carbon dioxide
Answer:
13.8 mol CO₂
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Using Dimensional Analysis
- Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
Explanation:
<u>Step 1: Define</u>
8.32 × 10²⁴ molecules CO₂
<u>Step 2: Identify Conversions</u>
Avogadro's Number
<u>Step 3: Convert</u>
<u />
= 13.816 mol CO₂
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
13.816 mol CO₂ ≈ 13.8 mol CO₂
In a chemical change, a new substance is made, like when you burn a candle. In a physical change, no new substance is made, like when water turns to ice.
