Concept introduction:
The characteristic mass of a compound is the formula mass of the compound, which is obtained by adding the
A conversion factor is a numerical ratio, which is used to change one unit into another.
The chemical formula represents the precise number of atoms in a molecule, but not their structural arrangement.
