The densities of the coinage metals (copper, silver and gold) are as follows: copper = 8.95 g/cm3 silver = 12.59 g/cm3 gold = 19
ExtremeBDS [4]

1. The calculated density of the sample is 12.6 g/cm³

2. The sample is silver (option B)

<h3>Definition of density </h3>

The density of an object is defined as the mass of the object per unit volume of the object. Mathematically is expressed as:

Density = mass / volume

<h3>1. How to determine the density </h3>
  • Mass = 15.12 g
  • Volume = 1.20 cm³
  • Density =?

Density = mass / volume

Density = 15.12 / 1.20

Density = 12.6 g/cm³

<h3>2. How to determine the sample </h3>
  • Density of copper = 8.95 g/cm³
  • Density of silver = 12.59 g/cm³
  • Density of gold = 19.32 g/cm³
  • Calculate density = 12.6 g/cm³
  • Sample =?

From the above we can see that the calculated density is the approximate density of silver.

Therefore, the sample is silver
