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

Need to review unit conversions and/or dimensional analysis?
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).
