SubstanceDefinition is used for rich descriptions of substances, of any type, to support the detailed definition of medications, and in particular their ingredients (see Ingredient) and manufacturing.. This is a … Relative atomic mass is determined by the average atomic mass, or the weighted mean of the atomic masses of all the atoms of a particular chemical element found in a particular sample, which is then compared to the atomic mass of carbon-12. This comparison is the quotient of the two weights, which makes the value dimensionless (having no unit). This quotient also explains the word relative: the sample mass value is considered relative to that of carbon-12.

Webrelativistic mass, in the special theory of relativity, the mass that is assigned to a body in motion. In physical theories prior to special relativity, the momentum p and energy E assigned to a body of rest mass m0 and velocity v were given by the formulas p = m0v and E = E0 + m0v2 /2, where the value of the “rest energy” E0 was undetermined.
