Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

The molar mass represents not a single atom or molecule but it represents Avogadro's number of atoms or molecules. The formula CS, represents 76.15 g (1 mole) of carbon disulfide. The percentage of sulfur by mass can be calculated as follows: 2S/1 CS₂ = (64.14 g S/76.15 g CS₂) x 100 = 84.22% S The following are examples how the mole concept is applied 1.
