Morphology
The meaning 'ratio of the density of a substance to the density of a standard' is directly derivable from combining 'relative' (in relation to something) with 'density' (mass per unit volume), so a learner who knows both constituents can infer it denotes a comparative measure. This compositional, technical naming pattern is cross-linguistically common in scientific vocabulary, making it transparent to B1 learners familiar with the words.
Etymology
Relative density comes from joining relative ('compared to something else') and density ('how heavy something is for its size'). It means how heavy a substance is when you compare it with a standard such as water or air, so scientists use it to tell if something will float or sink.
