Chapter 9: Chemical Quantities (~27%)
I.
Information from Chemical Equations
- must follow the Law of Conservation of Mass (i.e. the reactions must be balanced)
- coefficients of balanced chemical reactions can represent moles or molecules
II.
Chemical Equations and Stoichiometry
A.
Mole  Mole Relationships
- given moles of a reactant or product you need to be able to use the
stoichiometric relationships given in the balanced chemical equation to
convert to moles of any other reactant or product
-pictorial representations of chemical reactions
B.
Mass  Mole  Mole  Mass Relationships
- given mass of a reactant or product you need to be able to use the
stoichiometric relationships given in the balanced chemical equation to
convert to the mass of any other reactant or product
C.
Limiting Reactants
- Calculate Theoretical yields
- Calculating the amounts of reactants that are left after a reaction is
complete
D.
Percent Yield

I.
Solution Composition
A.
Properties of Solutions

- Molarity (aka concentration)
- making a solution with a known molarity
- molarity as a conversion factor
- calculating the concentration of compounds
- calculating the concentration of ions
C.
Dilution
- what is going on when we dilute a solution (i.e. what is happening to the number of
moles of solute?)
- Calculations (M1V1=M2V2)
