• Day 5 (Jan 22-23): Review and Test

5. Learning Objectives
• I can set up conversion problems using units and
mole mountain
• I can convert between moles and particles
• Vocabulary: None

6. Investigation
• In your lab notebook, write the heading:
Unit 5 Day 2 Investigation
• Under your heading number 1 – 10.
• Do not write on your investigation sheet!
• Follow the instructions, and answer the
questions in your lab notebook.

7. Notes/Lecture
• Prepare your Cornell Notes paper
• Topic: Mole – Particle Conversions
• Don’t forget the date!
• No electronics
• No talking
• Raise your hand with questions
• EVERYONE takes notes.

8. Quick Review
• What is a mole?
– Unit of matter
– 6.02 x 1023
• What is mole mountain?
Mole
Grams Particles
(or atoms or
molecules)

9. How do I set up a conversion between
moles and particles?
Moles
It’s ONE step!
Grams Particles
(or atoms or
molecules)

10. How do I set up a conversion between
moles and particles?
• Remember!
– To convert particles to moles:
Particles x Moles
Particles
– To convert moles to particles:
Moles x Particles
Moles

11. What conversion factor do I use?
• 1 mole = _?_ particles
– 6.02 x 1023 particles
____1 mole_____ OR 6.02 x 1023 particles
6.02 x 1023 particles 1 mole

12. How do I convert between moles and
particles?
• How many particles are in 4 moles?
– Which unit do you have? (given)
• MOLES
– What unit do you want?
• PARTICLES
4 moles x 6.02 x 1023 particles
1 mole
4 x 6.02 x 1023 particles =
2.41 x 1024 particles

13. How do I convert between moles and
particles?
• How many moles are in 4.82 x 1024 atoms?
– Which unit do you have? (given)
• ATOMS
– What unit do you want?
• MOLES
4.82 x 1024 atoms x 1 mole
6.02 x 1023 atoms
4.82 x 1024 = 8 moles
6.02 x 1023

14. Summary
• Summarize how to convert between moles
and particles IN YOUR OWN WORDS under
your notes!

15. Independent Practice
• If you get stuck
– Look at your notes
– Ask your partner
– Raise your hand

16. Exit Slip
• Everything off your desk except for your tracker sheet.
• Once your exit slip is graded, write your mastery score
in your tracker.
-> 1/5 = 20%
-> 2/5 = 40%
-> 3/5 = 60%
-> 4/5 = 80%
-> 5/5 = 100%
• If you achieved at least 80% mastery, put a sticker up!
