Use Dimensional AnalysisExplanation:

Step 1: Define

[Given] 3.2 × 10²⁴ atoms Si

[Solve] grams Si

Step 2: Identify Conversions

Avogadro's Number

[PT] Molar Mass of Si - 28.09 g/mol

Step 3: Convert

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

Step 4: Check

Follow sig fig rules and round. Instructed to round to 2 sig figs.

149.266 g Si ≈ 150 g Si

The answer is !

The correct answer is "hydrogen".
