Question

Define the relative density of a substance.Why does relative density have no units

those me a good answer I will mark him brainliast​

Answer 1

Answer:

the relative density does not have a unit because it is a ratio of two-dimensionally same quantities

• . Note: When we divide two-dimensionally the same quantity they get cancelled and their ratio is dimensionless. The relative density concept is highly used in the pressure measurement of the fluids.

Answer 2

Answer:

Relative density has no unit because it is the ratio of same units which gets cancelled. Answer: ... Relative density = Density of the substance/Density of water at 4°C. As both the numerator and the denominator on the RHS of the above formula has the same unit (i.e. kg/m3) they get cancelled.24-
