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.
