Chapter 4 Stoichiometry Dr. Manuel P. Soriaga Department of Chemistry Stoichiometry Stoichiometry is a term used to describe quantitative relationships in chemistry “How much?” of a product is produced (or reactant consumed) Balanced chemical equation will be needed Conversion between mass to number of moles (and vice-versa) will usually be required Stoichiometry from Balanced Chemical Equation 1 molecule of methane (CH 4 ) reacts with 2 molecules of oxygen (O 2 ) to produce one molecule of carbon dioxide (CO 2 ) and 2 molecules of water (H 2 O) 1 mole of CH 4 reacts with 2 moles of O 2 to produce one mole of CO 2 and 2 moles of H 2 O N A molecules of CH 4 reacts with 2 N A molecules of O 2 to produce N A molecules of CO 2 and 2 N A molecules of H 2 O 16 g of CH 4 reacts with 64 g of O 2 to produce 44 g of CO 2 and 36 g of H 2 O a A b B a moles A mass A b moles B mass B stoichiometric factor Reaction Stoichiometry Relationships × MW ÷ MW × MW ÷ MW Stoichiometric Factors from Balanced Chemical Equations: Zn (s)
