atomic mass
This term is a technical specification used primarily in chemistry and physics to describe the mass of a single atom. It is distinct from molar mass, which refers to the mass of one mole of a substance, although the numerical values are often identical.
Because it describes a specific physical property of an element, it is treated as an uncountable noun. It does not typically take a plural form in scientific discourse, as the concept refers to a constant value for a specific isotope or a weighted average for an element.
