Concentration

Concentration kinds are not freely interchangeable. Conversions between amount- and mass-based units need the molecular weight; conversions involving mass fraction need the solution density (never assumed). Volume fraction (% v/v) converts only within itself.

Molecular weight (g/mol)

Required only for amount ↔ mass conversions.

Solution density (g/mL)

Required only for conversions involving mass fraction. Never assumed.
