The preparation and dispensing of medications rely on precise chemical measurements. Pharmacists must calculate dosages, concentrations, and compound mixtures accurately to ensure patient safety and therapeutic effectiveness. The mole concept underpins these calculations, enabling pharmacists to convert between mass, volume, and number of molecules or ions in a drug. Misunderstandings or errors in mole-based calculations can lead to underdosing or overdosing, with potentially serious health consequences.
