Answer:
2.0 × 10⁻²³ g C
General Formulas and Concepts:
Chemistry - Atomic Structure
- Using Dimensional Analysis
- Avogadro Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
Explanation:
Step 1: Define
1 atom C
Step 2: Identify Conversions
Avogadro Number
Molar Mass of C - 12.01 g/mol
Step 3: Convert
[tex]1 \ atom \ C(\frac{1 \ mol \ C}{6.022 \cdot 10^{23} \ atoms \ C} )(\frac{12.01 \ g \ C}{1 \ mol \ C} )[/tex] = 1.99435 × 10⁻²³ g C
Step 4: Check
We are given 2 sig figs. Follow sig fig rules and round.
1.99435 × 10⁻²³ g C ≈ 2.0 × 10⁻²³ g C
