7. Mole Review
We will review some mole concepts and practice problems together as a class before we try a problem set

8. Review Questions What is Avogadro’s number?
6.02 x 1023
What are the 3 types of particles?
Atoms, molecules and formula units
When is matter referred to as an atom?
When it is a pure element
When is a compound referred to as a formula unit?
If the compound is ionic
When is a compound referred to as a molecule?
When it is covalent

9. Review Questions Continued
What conversion factor is used to convert from mass to moles?
Molar Mass
What conversion factor is used to convert from moles to particles?
Avogadro’s number

10. Practice Problem 1
How many moles of AgNO3 are in 3.47 g of AgNO3?

11. Practice Problem 2
How many molecules of H2O are in moles of H2O?

12. Practice Problem 3
How many formula units of NaCl are in g of NaCl?

13. Converting from moles to Liters
Use the conversion factor 22.4 L = 1 mole
Example: What volume does 2.5 moles of O2 gas occupy?

14. Mole Conversion Practice
Complete the practice problems at your desk. Selected responses will be reviewed as a class. Problems not completed in class will be completed at home.
