For a substance, which displaces 8.1 grams of water with a mass of 16.2 grams of water, the value of specific gravity is 2.
The specific gravity of a substance is the ratio of the density of the given substance to the density of the other substance.
The density [tex]\rho_s[/tex] of a material is mass per unit volume. Its specific gravity with reference to the other is given as,
[tex]g_s=\dfrac{\rho_s}{\rho_r}[/tex]
Given information-
The mass of the substance is 16.2 grams of water.
The displacement of the water is 8.1 grams.
As the mass of substance given in the terms of water, thus the ratio of density of the substance to the density of water is equal to their masses.
Thus the specific gravity of the substance is,
[tex]g_s=\dfrac{16.2}{8.1}\\g_s=2[/tex]
Hence, for the substance which displace 8.1 grams of water with a mass of 16.2 grams of water, the value of specific gravity is 2.
