The mole concept is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. However, the mole allows a chemist to work with amounts large enough to use.
Define the amount unit mole and the related quantity Avogadro’s number
Define the amount unit mole and the related quantity Avogadro’s numberExplain the relation between mass, moles, and numbers of atoms or molecules, and perform calculations deriving these quantities from one another
The Mole
The MoleThe identity of a substance is defined not only by the types of atoms or ions it contains, but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule,
