Root Explanation

Equimolar → It is formed from "equi-" (from Latin "aequus", meaning equal) and "molar" (from Latin "molaris", meaning pertaining to a mass or a large quantity). The word "equimolar" refers to solutions that have equal concentrations of solute in a given volume.

Memory Tip

Think of 'equal' ('equi-') and 'mass' ('molar') to remember that 'equimolar' means having equal amounts of substance.
