Question

Explain density and relative density and write their formulae

Answer 1

Hey mate ❤

DENSITY
Some substances appear to be heavy whereas others are light. For example, iron is heavier than aluminium and water is heavier than alcohol. In physics, we describe the lightness all heaven is of different substances by using the word density. THE DENSITY OF A SUBSTANCE IS DEFINED AS THE MASS OF SUBSTANCE PER UNIT VOLUME.

$density = mass \: of \: substance \div volume \: of \: substance$
$density \: = mass \div volume$
The SI unit of density is kg/m
____________________________________

RELATIVE DENSITY
The relative density of a substance is the ratio of its density to that of water.
$relative \: density \: = density \: of \: substance \div density \: of \: water$

Hope it helps:)

Hola!!!!!❤️❤️❤️

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. Specific gravity usually means relative density with respect to water. The term "relative density" is often preferred in scientific usage.
The Density is expressed in Kg/L. The Density Formula is used to determine the density of any given body.

relative density or density is same

so its formula is Density=mass/volume

or

relative density is the density of a gas wrt to H2 gas
