Atomic Mass Unit: (amu) A small unit of mass equal to 1.66 X 10^-24 grams.
Average atomic mass: The weighted average of the masses of all the isotopes of an element.
Mole: The number equal to the number of carbon atoms in exactly 12 grams of pure 12(left superscript)C: Avogadro's number. Represents 6.022 X 10^23.
Avogadros number: The number of atoms in exactly 12 grams of pure 12(left superscript)C, equal to 6.022 X 10^23.
Molar Mass: The mass in grams of 1 mole of that substance.
Mass Percent: The percent by mass of a component of a mixture or of a given element in a compound.
Empirical Formula: The formula of a compound expressing the smallest whole-number ratio of atoms in a compound.
Molecular Compound: The actual formula of a compound giving the types of atoms and numbers of each type of atom.
