The mole (\(n\)) is an important unit of measurement in chemistry because it allows scientists to count and quantify atoms, molecules, and ions in a given sample. This then allows them to perform calculations relating to chemical reactions. In everyday language, we use \(1\) dozen \(=12\) object, \(1\) dozen \(=10\)...
