  1. Moles

  2. Review of Moles Molar Mass – Mass of one mole of any substance. Found by using the masses on the periodic table. How do find the molar mass of sodium oxide?

  3. Converting Moles to grams Keep in mind: Moles are small numbers; grams are large numbers. How do you convert 3.5 moles of sodium oxide to grams?

  4. Converting Grams to Moles How do I convert 78.5 g of sodium oxide to moles?

  5. Converting to Atoms/Formula Units/Molecules Ionic compounds (Na2O) are called formula units. Molecular compounds (C2H6) are called molecules. Atoms (Al) don’t change. Equal to atomic mass from periodic table. 1 mole of atoms/formula units/molecules = Avogadro’s number. (remember mole day???) 1 mole = 6.02 x 1023atoms/formula units/molecules Therefore, molar mass of XY = 6.02 x 1023 molecules of XY

  6. Converting to Atoms/Formula Units/Molecules How do I convert 3.5 moles of sodium oxide to formula units?
