1. Stoichiometry

2. Stoichiometry Stoichiometry
Stoichiometry is the process of using an equation to determine the exact amount of chemicals given off in a reaction.

3. Moles of A Moles of B Grams of A Grams of B Moles of A = Moles of B
Use the balanced equation
Molar mass A = 1 mole of A
Use the periodic table
Moles of A
Moles of B
Grams of A
Grams of B
Molar mass B = 1 mole of B

4. Practice Problem One
How many grams Li2 will be produced from 12g of bismuth dilithide?
BiLi3  Bi2 + Li2

5. Practice Problem Two
How many grams of fluorine gas (F2) are needed to produce 25g of FCl?
F2 + Cl  FCl

6. Practice Problem Three
How many grams of sodium are needed to completely react with 75g of Sb2?
Na + Sb2  Na3Sb
