Stoichiometry Easy as 1, 2, 3!!!

Stoichiometry • The study of the relationships or ratios between two or more substances undergoing chemical reactions ***Must balance reaction 1 st before solving***

Mole Ratio • In a balanced equation you can create ratios from one compound to another creating a bridge conversion factor __ Mg + __ O 2 __ Mg. O

MASS TO MASS

Diving In (Practice) If you have 6. 85 g of phosphorus how much oxygen gas (in grams) do you need to combine with it? __ P + __ O 2 __ P 4 O 10

Practice If you begin with 200 g of sodium hydroxide how many grams of sodium sulfate will be produced? Na. OH + H 2 SO 4 H 2 O + Na 2 SO 4

Practice If you are give 8 g of oxygen gas how many grams of product can be produced? __ P + __ O 2 __ P 4 O 10

Practice If you produce 250 g of Li 2 SO 4 how many grams of Li. NO 3 did you begin with? Pb(SO 4)2 + Li. NO 3 Pb(NO 3) 4 + Li 2 SO 4

Practice If you create 7. 46 g of P 4 O 10 how many grams of phosphorus would you need to start with? __ P + __ O 2 __ P 4 O 10

MASS TO VOLUME

Practice In the following reaction 13. 5 L of Oxygen reacted with the mercury. How many grams of Mercury (I) Oxide were formed? Hg + O 2 Hg 2 O

Practice In the following reaction you react 48 grams of Oxygen with an unknown volume of hydrogen to form water. How many liters of hydrogen were used? O 2 + H 2 O

VOLUME TO VOLUME

Practice Nitric Oxide (NO) reacts instantly with oxygen gas to give Nitrogen Dioxide, a dark brown gas. If you finished with 65. 2 liters of Nitrogen Dioxide, how many liters of Oxygen were used? NO + O 2 NO 2

PERCENT YIELD
