Chemistry - Calculations associated with chemical analysis by chemical
reactions; the MOLE concept
Calculations associated with chemical analysis by chemical reactions; the
Measurements of amounts of materials are generally made by mass or volume.
These quantities alone cannot provide direct insight into chemical formulae
or the relative amounts of elements and compounds reacting or being
produced in chemical reactions.
The key to chemical formulae and chemical reactions is relative numbers of
specified particles - atoms, ions or molecules. Direct links between
measured amounts of elements or compounds and numbers of specified
particles are established by applying of the mole concept to chemical
