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
