Explanation:

Step 1: Define

6.00 g C

Step 2: Identify Conversions

Avogadro's Number

Molar Mass of C - 12.01 g/mol

Step 3: Convert

$6.00 \ g \ C(\frac{1 \ mol \ C}{12.01 \ g \ C} )(\frac{6.022 \cdot 10^{23} \ atoms \ C}{1 \ mol \ C} )$ = 3.00849 × 10²³ atoms C

Step 4: Check

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

3.00849 × 10²³ atoms C ≈ 3.01 × 10²³ atoms C
