Explanation:

Step 1: Define

8.02 × 10²⁴ atoms Hg

Step 2: Identify Conversions

Avogadro's Number

Molar Mass of Hg - 200.59 g/mol

Step 3: Convert

  1. Set up:                               [tex]\displaystyle 8.02 \cdot 10^{24} \ atoms \ Hg(\frac{1 \ mol \ Hg}{6.022 \cdot 10^{23} \ atoms \ Hg})(\frac{200.59 \ g \ Hg}{1 \ mol \ Hg})[/tex]
  2. Divide/Multiply:                                                                                               [tex]\displaystyle 2671.42 \ g \ Hg[/tex]

Step 4: Check

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

2671.42 g Hg ≈ 2670 g Hg
