Question

what is relative density . calculate the relative density of glass​

Answer 1

Answer:

Relative density, or specific gravity,[1][2] is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. The term "relative density" is often preferred in scientific usage. It is defined as a ratio of density of particular substance with that of water.

Answer 2

Answer:

Relative density:

The relative density of a substance is the ratio of the density of that substance to the density of water at 4° C.

Relative density = Density of substance / Density of water at 4° C.

Relative density of a substance is also defined as the ratio of the mass of a certain volume of a substance to the mass of an unequal volume of water at 4° C.

Since relative density is a pure ratio, it has no unit.

It is a scalar quantity

Relative density = Density of substance / Density of water at 4° C.

Therefore, The relative density of glass is 2.5
