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

Juliette [100K]

D, because matter does not change in space but unlike gravity, which changes, matter, is the mass of it, which will stay the same unless there is a chemical change or, physical change, but not in this case, so the answer you are looking for is D. hope this enlarged your understanding and knowledge.
