Question #617b0

1 Answer

Answer:

Density is the mass of an object per unit volume, whereas relative density is the ratio of the density of an object to the density of a reference material (usually water).

Explanation:

  1. Density is the mass of a unit volume and relative density is the
    ratio of the density of a substance to the density of the reference material.
  2. Density has units but relative density does not.
  3. Density may have different numerical values depending on its units but relative density has a constant value.
