Question

what is the difference between the density
and relative density of subtance ?​

Answer 1

Explanation:

Density is a measurement that compares the amount of matter an object has to its volume. An object with much matter in a certain volume has high density. ... Density is found by dividing the mass of an object by its volume.

Relative density.

Relative density (R.D) of a substance can be calculated by dividing density of a substance with the density of water. For example, Thus, Relative density of iron is 8.5 (No unit is applied). Density of a substance can be calculated by multiplying Relative Density (R.D.) of the substance with the Density of water.

• Density is defined as mass per volume. Density of a material is the amount of substance contained in unit volume of the material. SI unit of density is kg/m3.

• Relative density is the ratio of density of a substance to the density of a reference material. Usually, the reference material is water. Relative density is also known as specific gravity.
