What is millimol and milli equivalent?

Answer 1

A millimole (mmol) is a unit of measurement that represents one-thousandth of a mole, which quantifies the amount of a substance based on the number of particles, atoms, or molecules. A milliequivalent (mEq) is a unit used to express the concentration of reactive species in a solution, particularly ions, and is based on the chemical reactivity of the species involved. It accounts for the charge of ions, where one milliequivalent is equal to one-thousandth of an equivalent, determined by the number of charges per mole. Thus, while millimoles measure the quantity of a substance, milliequivalents consider both quantity and reactivity.
