The Magic of Avogadro’s
Number
• Remember what you learned earlier about
Avogadro’s magical number. Our way of
counting atoms and molecules is to take
their masses on the atomic level (amu) and
translate them directly into grams. The
gram atomic or gram molecular mass of an
element or compound = 1 mole of that
substance or 6.02 x 10 23 particles.
