Stoichiometry deals with quantities involved in chemical reactions. The law of conservation of mass tells us that matter is not created or destroyed during chemical reactions. The law of definite proportions tells us that specific substances are composed of the same elements in the same proportions by mass. Because of these laws, we can predict both accurately and consistently the quantities of substances and energy involved in chemical reactions.
