Answer:
2.6
Explanation:
Given that,
The density of a mineral is 2.6 g/cm³
The ratio of the density of mineral to the density of water is called is specific gravity.
We know that, the density of water is 1 g/cm³
So,
[tex]SG=\dfrac{2.6\ g/cm^3}{1\ g/cm^3}\\\\SG=2.6[/tex]
So, its specific gravity is 2.6.
