The ring is made up of silver. This statement is true.
It is given that the mass of a silver ring is 21 g.
Volume is 2 [tex]cm^{3}[/tex]
We need to determine if the ring is made up of silver or not.
As we know that density is defined as the ratio of mass and volume.
The density of silver is [tex]10.49gm/cm^{3}[/tex].
If the calculated value comes out to be same, it is made of silver, otherwise not.
Now,
Density = [tex]\frac{Mass}{Volume}[/tex]
[tex]=\frac{21}{2}[/tex]
[tex]10.50gm/cm^{3}[/tex]
It is approximately same. Hence the ring is made of silver.
