Answer:

In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. ... Electrical forces are extremely sensitive to distance.

<h3>Explanation:</h3>

<u>Step 1: Define</u>

3.7 g Au

<u>Step 2: Identify Conversions</u>

Avogadro's Number

Molar Mass of Au - 196.97 g/mol

<u>Step 3: Convert</u>

<u /> $3.7 \ g \ Au(\frac{1 \ mol \ Au}{196.97 \ g \ Au} )(\frac{6.022 \cdot 10^{23} \ atoms \ Au}{1 \ mol \ Au} )$ = 1.13121 × 10²² atoms Au

<u>Step 4: Check</u>

<em>We are given 2 sig figs. Follow sig fig rules and round.</em>

1.13121 × 10²² atoms Au ≈ 1.1 × 10²² atoms Au
