Root Explanation

Millimolar → It is formed from "milli-" (meaning one thousandth) and "molar" (from Latin "mola", meaning mass or mill). The term "millimolar" refers to a concentration of one thousandth of a mole per liter, commonly used in chemistry to describe very dilute solutions.

Memory Tip

Think of 'milli-' meaning one thousandth, and 'molar' relating to mass or concentration. This helps you remember that 'millimolar' refers to a very small concentration in solutions.
