it is cuz relative density = density of substance/density of water at 4oC.
ie. if density of substance is 300 gm cm-3
and density of water is 1 gm cm-3
therefore : = 300 gm cm-3 / 1 gm cm-3
as gm cm-3 is on both side it gets cancelled n

THRE IS NO UNIT FOR RELATIVE DENSITY
expressed in unified atomic mass unit, amuHowever, for practical purposes in the laboratory the relative atomic mass is used so the unit would be gram. (Relative atomic mass compares the mass of all elements to that of the carbon-12 isotope taken as exactly 12)
The relative mass of a neutron compared with a proton is one.
The unit used to measure weighted average atomic mass is atomic mass unit (amu). This unit is a standard for atomic and molecular mass measurements in chemistry and is defined as one twelfth of the mass of an atom of carbon-12.

At the bottom, the atomic number is at the top.
Atomic mass is the measure of a mass of one atom in relation to 1/12 mass of Carbon 12 atom and measured in atomic mass unit(amu) or Dalton unit or grams/mol.Relative atomic mass is also the relative mass but does not have a unit but a ratio number.
Atomic mass is measured in a unit called an "atomic mass unit". This unit is defined as 1/12 of the mass of a carbon-12 atom at ground state.An atomic mass unit is approximately 1.66053886 x 10-27 kg.Atomic mass is measured in atomic mass units (amu) and Daltons.

relative atomic mass
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
At the bottom, the atomic number is at the top.
The Atomic Mass of Magnesium is 24, the RAM (relative atomic mass) is 24.305.
The unit of atomic mass for aluminum is atomic mass unit (amu) or unified atomic mass unit (u).
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
