Question

write si unit of density.why relative density have no unit

Answer 1

Density=mass/volume

Therefore it's unit is kg/m³

Relative density is defined as the ratio of density of the substance with any standard density.since it is a ratio that is why it has no unit

Answer 2

hey mate !!!

answer :-

si unit of density is g/cm³

relative density has no units beacuse the two quantities divided to get relative density are same.

ex :- 25 g/cm³÷5g/cm³=5

g/cm³ will be cancelled.
