Question

explain between density and relative density with formula​

Answer 1

$\huge{\boxed{\boxed{\mathfrak{AnSwEr}}}}$

Relative density can be calculated directly by measuring the density of a sample and dividing it by the (known) density of the reference substance. The density of the sample is simply its mass divided by its volume.

Answer 2

Answer:

Definition of Density:

Density of an object can be defined as the mass of an object in a given volume.

Formula:

So, Density = Mass / Volume

Example:

Mass = 33.5 kg

Volume = 10$cm^{3}$

Therefore, Density = 33.5/10 = 3.35 kg/$cm^{3}$

Definition of Relative Density:

The relative density of a substance is the ration of its density to that of water

Formula:

Relative Density = Density of substance / Density of water

Example:

Density of substance = 1.42 g/$cm^{3}$

Density of water = 1g/$cm^{3}$

So, Relative density = 1.42 / 1 = 1.42  [Note that there is no unit of relative

                                                             density because it is a ratio]
