What is stoichiometry? The relationship between the quantities of substances taking part in a chemical reaction. ________________________________ You must always have a balanced chemical equation to perform stoichiometric calculation problems.

Type 1: Mole to Mole Problems General Setup: THIS RATIO COMES FROM YOUR BALANCED CHEMICAL EQUATION!

Example Problem: How many moles of ammonia (NH3) are produced from 9 Example Problem: How many moles of ammonia (NH3) are produced from 9.1 moles of hydrogen gas (H2)? ___H2 + ___N2  ___NH3

Type 2: Mole to Gram Problems THE MOLAR MASS IS OBTAINED FROM THE PERIODIC TABLE! General Setup: THIS RATIO COMES FROM YOUR BALANCED CHEMICAL EQUATION!

Example Problem: How many grams of nitrogen are needed to react with 13.4 moles of hydrogen gas (H2)? ___H2 + ___N2  ___NH3

Type 3: Gram to Mole Problems THIS RATIO COMES FROM YOUR BALANCED CHEMICAL EQUATION! General Setup: THE MOLAR MASS IS OBTAINED FROM THE PERIODIC TABLE!

Example Problem: How many moles of chlorine are needed to react with 5 Example Problem: How many moles of chlorine are needed to react with 5.4 grams of sodium? ___Na + ___Cl2  NaCl

Type 4: Gram to Gram Problems THIS RATIO COMES FROM YOUR BALANCED CHEMICAL EQUATION! General Setup: THE MOLAR MASS IS OBTAINED FROM THE PERIODIC TABLE! THE MOLAR MASS IS OBTAINED FROM THE PERIODIC TABLE!

Example Problem: How many grams of nitrogen are needed to react with 4 Example Problem: How many grams of nitrogen are needed to react with 4.5 grams of oxygen? ___N2 + ___O2  ____N2O5

___Na(OH) + ____H2(SO4)  ____H(OH) + ___Na2(SO4) Using the equation above: MOLE to MOLE: How many moles of water will be produced from 7.6 moles of H2O? MOLE to GRAM: How many grams of water will be formed from 3.9 moles of sodium hydoride? GRAM to GRAM: many grams of sodium sulfate will be formed if you start with 200 grams of sodium hydroxide and you have an excess of sulfuric acid?

___Pb(SO4)2 + ____Li(NO3)  ____Pb(NO3)4 + ____Li2(SO4) Using the equation above: How many grams of lithium nitrate will be needed to make 250 grams of lithium sulfate, assuming that you have an adequate amount of lead (IV) sulfate to do the reaction? How many moles of lead (IV) sulfate will be produced from 5.6 moles of lithium nitrate? How many moles of lithium nitrate are needed to react with 0.67 grams of lead (IV) sulfate?
