Measure/Reference
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.
