The number of moles of a substance can be converted into molecules by: a Multiplying them by their molar mass b Dividing them by their molar mass c Dividing them by Avogadro's number dultiplying them by Avogadro's number

To convert moles of a substance into molecules, you simply multiply the number of moles by Avogadro's number, which is approximately \(6.022 \times 10^{23}\). This fundamental relationship allows chemists to bridge the gap between the macroscopic scale of substances we handle in the lab and the microscopic world of individual atoms and molecules. In real-world applications, understanding how to convert moles to molecules is crucial in fields like pharmacology. For instance, when preparing medications, calculations based on moles help pharmacists determine the precise number of molecules needed to achieve desired therapeutic effects, ensuring accuracy and safety in dosing.
