We present results of an investigation of factors that set values of relative atomic mass mr and the atom's internal energy E<inf>int</inf>. The results do suggest the possibility for a consistent formalism for accurate evaluation of m<inf>r.</inf> It is shown that: (i) Avogradro constant (Loschmidt number) can be evaluated from fundamental principles to yield N<inf>A</inf>=6.623×1043 u/mol; (ii) A clear distinction exists between the transverse e-m radiation, c=2.99792458×108 m/s, normally associated with speed of light in "vacuum" and the same radiation of tangible matter described here as "molar" radiation c∗=co=c′=3.715352291×10-14 m/s; for a given v, c determines values of absolute atomic mass, i.e., m=hv/c2 and co sets values of relative atomic mass, e.g., mo<inf>r</inf> = hvo<inf>r</inf>=co2; (iii) co is identifiable with the cosmic microwave background revealing that the latter is actually intrinsic e-m radiation of tangible matter; (iv) complete description of the atom's internal energy requires not one but combinations of the parameters v, m, and c as each relates to the atom's wave or particulate form and its domain; (v) with v<inf>e</inf>=1.0 Hz Planck constant turns out to be a measure of the electron's internal energy and indeed nature's fundamental energy unit; (vi) macrocosmic matter and energy constitute only 0.02% and 0.01% of total cosmic values, respectively, the bulk of 99.98% and 99.99% belongs, respectively, to invisible microcosmic (dark) matter and energy; and (vii) conversion of the particle (mass) to the wave (energy) does not destroy the atom's absolute mass.
