2.0 × 10⁻²³ g C

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

1 atom C

Step 2: Identify Conversions

Avogadro Number

Molar Mass of C - 12.01 g/mol

Step 3: Convert

= 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

the answer is 0.42 is that is an option. this question provides no info
