Morphology

molal + concentration

The phrase is compositional: 'molal' specifies the unit basis (moles per kilogram of solvent) and 'concentration' denotes the amount of solute per unit of solvent, so the combined meaning—concentration expressed in moles per kilogram—is directly derivable from the constituents. Although technical, it follows a regular adjective+noun pattern and similar unit-based constructions occur cross-linguistically, so a learner who knows both constituent meanings would understand it.

Etymology

Molal concentration comes from molal, which is based on the unit called a 'mole', and from concentration, so picture counting a fixed number of 'moles' put into exactly one kilogram of the liquid, the 'solvent'. That's why molal concentration means 'moles per kilogram of solvent' and does not change with temperature.
