Question

______ of a substance can be calculated by dividing density of a substance with the density of water.

• A. Absolute density
• B. Relative density
• C. Specific density
• D. All

Answer 1

Answer: (B)

Relative density

Relative density of a substance is defined as the ratio between the density of the substance to the density of water at ${40}^{o}C$. Relative density is also known as specific gravity. The relative density of a substance is a pure number without any unit. It tells how many times a substance is heavier than water.Relative density (R.D) of a substance can be calculated by dividing density of a substance with the density of water.
