Question

The dimensional formula for relative density is(a) [ML⁻³](b) [M⁰L⁻³](c) [M⁰L⁰T⁻¹](d) [M⁰L⁰T⁰]

Answer 1

d) is right option ......

Answer 2

Hey there!

Relative density of a substance is defined as the ratio density of substance to density of water.

It has no unit since units of density is division cancel each other.

So, it is dimensionless quantity.

We can represent dimensionless quantity as:

= M⁰L⁰T⁰
