Objective
Notes- Measuring Matter Elements
- How do scientists count the number of atoms, molecules, and
formula units?
- What is Avogadro’s number?
- How can particles be converted to moles and how can moles be
converted to particles?
- What is molar mass?
- How can moles be converted to mass and how can moles be
converted to moles?
Mole Activity
- How can the mass of a substance be converted first into moles
and then into atoms?
- What is the molar mass of an element?
- What units must accompany mole conversions in order to
obtain full credit?
- Why must the mass of the empty bottle be obtained first?
Notes- Particle to Mass Conversions
- How can a particle be converted to mass? Can that conversion
be done in one step?
- Can a mass be converted to a particle in one step? How many
steps does it take?
- Can students determine the steps necessary in all mole
conversion problems using logic instead of memorization?
Notes- Conversions Involving Compounds
- How can the molar mass be calculated for compounds?
- What is the molar mass of an element versus the molar mass of
a compound?
- Do the conversion equations change when calculated for a
compound versus an element?
- How can you determine which type of equation to use for a
calculation?
Quiz- Molar Mass Conversions
- How can moles be converted to mass of a compound?
- How can mass be converted to particles of a compound?
Moles in a Burning Candle Activity

Notes of Formula of a Hydrate
- How are hydrates named?
- What is a hydrate and how can the number of waters in a
hydrate be calculated?
- What are the steps to solving hydrate problems?
- Can a hydrate problem be solved without being given the ionic
compound?
Lab #15- Formula of a Hydrate Lab
- Can you determine the moles of water in a mole of hydrated
compound?
- How many waters are contained in hydrated Magnesium
sulfate?
- How can a hydrate be anhydrated?
- What would happen if this procedure were used for all
hydrates? Is that possible?
- How could the procedure be changed to make the lab run more
efficiently?
Notes- Percent Composition, Empirical and Molecular Formulas
-What is percent composition? What is the formula for percent
composition?
-What is an empirical formula?
-How can an empirical formula be calculated?
-What is the difference between an empirical and a molecular
formula?
-How can a molecular formula be calculated?
Smarties Percent Composition Activity
- Can students find the percent composition of each color candy
in a Smarties package?
- How do students find the correct masses for the “Smarties”
compound?
- How can the correct molecular formula be found for the
“Smarties” compound?
- Can students apply the percent composition concept to all
compounds?
Moles Review
- What is percent composition and how is it calculated to equal
exactly 100%?
- How can moles be converted to atoms and how can moles be
converted to mass?
- What is an empirical formula? What is a molecular formula?
How can both be calculated from percent’s?
- How can percent composition be calculated?
