Using Dimensional AnalysisExplanation:

Step 1: Define

[Given] 3.14 × 10²³ atoms C

[Solve] grams C

Step 2: Identify Conversions

Avogadro's Number

[PT] Molar Mass of C - 12.01 g/mol

Step 3: Convert

[DA] Set up:                                                                                                      [DA] Multiply/Divide [Cancel out units]:                                                        

Step 4: Check

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

6.26227 g C ≈ 6.26 g C
