Moles = Molarity x Volume
Moles = 2.0 x 0.50
= 1.0 mole

The volume of the gold chain is 4.18 cm³
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
With the above formula, we can determine the volume of the chain. Details below:
<h3>How to determine the volume of the gold chain</h3>
The following data were obtained from the question:
- Mass of gold = 80.7 g
- Density of gold = 19.3 g/cm³
- Volume of gold chain =?
Density = mass /volume
Cross multiply
Density × volume = mass
Divide both sides by density
Volume = mass / density
Volume of gold chain = 80.7 / 19.3
Volume of gold chain = 4.18 cm³
