What is the SI unit of density?​

Answer 1

Answer:

Q2 ans:The density is defined as the mass of the body per unit volume. The S.I unit of density is kg/m3. The relative density is defined as the ratio of the substance to the ratio of the reference substance. The unit on both numerator and denominator are the same. So relative density is a unitless property.
