Morphology

apothecaries' + weight

The phrase is transparently composed from 'apothecaries'' (the possessive of 'apothecary', i.e. a pharmacist) + 'weight', so a learner who knows both constituents can infer it refers to the weights used by apothecaries — in other words a (historical) system of weights. Although the term is somewhat archaic and domain-specific, its basic meaning is directly derivable from the parts.

Etymology

Apothecaries' weight comes from old pharmacy shops where the apothecary was an old 'pharmacist' who used small metal weights on a scale to measure powders and liquids exactly. So the phrase refers to the old system of 'weights' and measures used to make medicines.
