UNIT IV: Chemical Conversions
Avogadro's Number & the Mole, Molar Mass, Concentration

• The complete MOLE CONVERSION SUMMARY is two pages, and includes molarity and molality conversions in addition to the ones shown below.
• Here is a STUDY GUIDE  for the Unit 4 Test!
• You might want to REVIEW THESE CHARTS, which can help you decide which conversion to use.

On your grade:

• The Mole (Reading, WS)
• Optional Skyward: Molar Mass
• Day 18 Quiz*
• Mole Conversions WS
• Skyward: Moles*
• Day 19 Quiz*
• Concentration WS
• Optional Skyward: ConcentrationCheck
• Required Skyward: Unit 4 Review
• Unit 4: Mole Conversions Test​
• Post Test: Basic Molar Relationships (The only new concept here is the final column.  It is explained in this reading handout.)

*If you missed this, you need to come to the classroom to make it up.  It is in the Quiz/Skyward binder at the front of the room.

In your notebook:

• Reading Assignment: The Mole
• Unit 4 Notes 1: Mole Conversions (pdf, printer-friendly)
• Unit 4 Notes 2: Concentration (pdf, printer-friendly)
• Tutorial: Dimensional Analysis 
• Tutorial: The Mole
• Tutorial: Calculating Molecular Weight 
• FYI: "Molecular Weight" is essentially the same thing as "molar mass", "formula mass" or "molecular mass."  Sometimes the word "mass" is replaced by the word "weight" (even though we're measuring in grams, so it is definitely a mass, not a weight).
• Tutorial: Using Molecular Weight
• Tutorial: Molarity
• Unit 4 Review Outline
• Post Test Reading
