1 The relative atomic mass, or atomic weight, of an element is the weighted average of the masses of the isotopes in the naturally occurring element relative to the mass of an atom of the carbon-12 isotope which is taken to be exactly 12.
Calculate the density once you know the volume and mass of the substance or object. Density is equal to the mass of the substance divided by its volume: D (density) = M (mass) / V (volume). Remember that a substance or object with a higher density has a higher measure of mass per unit of volume. A substance with a density that is greater than 1 gram/centimeter cubed will sink in water because it is denser.
