Reading a Periodic TableUsing Dimensional AnalysisAvogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.Explanation:

Step 1: Define

3.93 × 10²⁴ molecules CCl₄

Step 2: Identify Conversions

Avogadro's Number

Molar Mass of C - 12.01 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of CCl₄ - 12.01 + 4(35.45) = 153.81 g/mol

Step 3: Convert

Set up:                              Multiply:                                                                                                            

Step 4: Check

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

1003.77 g CCl₄ ≈ 1000 g CCl₄
