Question

Write a note on relative density

Answer 1

Answer:

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.

1. Urine normally has a specific gravity between 1.003 and 1.030. ...
2. Blood normally has a specific gravity of approximately 1.060.

I hope this will be help you.

Answer 2

Answer:

Explanation:

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 for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" is often preferred in scientific usage.
