Morphology

molar + concentration

The meaning is fully compositional: 'molar' specifies a concentration in moles per liter and 'concentration' denotes the amount of substance per volume, so together they denote amount of solute per liter measured in moles. This is a regular adjective + noun technical term (common across languages in chemistry), so a learner who knows both constituents can predict the overall meaning.

Etymology

The term molar concentration gives a simple picture: imagine a one-liter bottle and count how many 'moles' (a very large group of tiny particles) are inside. The part molar points to those 'moles' and concentration shows how many are in 'one liter', so it means 'moles per liter'.
