MOLAR MASS the mass, expressed in grams, of 1 mole of a specific substance. Conversely,
one mole is the amount of the substance needed for the molar mass to be the
same number in grams as the atomic mass of that substance.
EXAMPLE: The atomic weight of Carbon is 12 therefore the molar mass of
Carbon is 12 grams. Conversely, one mole of carbon equals the amount of
carbon atoms that weighs 12 grams.
Atomic weights can be found on any Periodic Table of Elements.
