Is Atomic Mass Density The mass of an element that is numerically equal to the atomic mass A in grams is called a mole and will contain Avogadro’s number N A of nuclei. If the density ρ of the material is known, then the number of nuclei per unit volume n can be calculated from n =ρN A /A. This is useful in calculating the cross section for nuclear scattering. The chart shows that atomic size and mass for the first 20 elements in
