Root Explanation

Molal is derived from the Latin word "mola" (meaning millstone) combined with the suffix "-al" (meaning pertaining to). The term "molal" refers to a concentration unit that is related to the number of moles of solute per kilogram of solvent, thus connecting the concept of a millstone to the measurement of concentration in solutions.

Memory Tip

Think of 'mola' as a millstone that grinds substances, and remember that 'molal' relates to measuring the concentration of a substance in a solution.
