Definition
quality that is the quality of a molecular entity or population of molecular entities, and is either the mass of one mole of that single entity, or the average mass of one mole of molecules in the population
Explanatory Notes
1) Molar mass is mass divided by amount of substance and is expressed in units such as grams per mole or kilograms per mole. 2) When molar mass is the quality of a molecular entity, it represents the mass per mole of molecular entities of the same kind as that entity. For a non-uniform molecular entity population, it may be a specified molar-mass average, and the averaging method should be recorded with the measurement result. 3) The numerical value of a molecular mass expressed in daltons and the corresponding molar mass expressed in grams per mole are conventionally equal, but they are different quantities with different dimensions.
Examples
- The molar mass for a population of high density polyethylene polymer is 300 000 g/mol; molar mass of glucose is 180 g/mol; molar mass of sodium chloride is 58.44 g/mol

Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
There are insufficient constructs to define necessary and sufficient conditions.
Formal Axioms
First-Order Logic Axioms
MolarMass(x) → Quality(x) ∧ ∃m ((MolecularEntity(m) ∨ MolecularEntityPopulation(m)) ∧ qualityOf(x, m))
Semi-Formal Natural Language Axioms
if x is a ‘molar mass’ then x is a ‘quality’ that is the ‘quality of’ some ‘molecular entity’ or some ‘molecular entity population’
