M/R	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.
