Mass per volume
Mass concentration relates the mass of a component to the mixture volume. mg expresses mass; mg/mL expresses mass concentration. Other concentrations, such as mol/L, describe a different quantity and cannot be compared directly without further information.

A document-reading example
A table column labeled amount in mg and another labeled concentration in mg/mL answer different questions. Copy the complete heading and unit. If the source gives only a mass, record concentration as undocumented.

Questions about this reference
Does more mg always mean a more concentrated solution?
No. Mixture volume also matters; mass alone cannot settle the comparison.
