The molar mass of a substance is the mass, expressed in grams, of 1 mole of that 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 12.011 therefore the molar mass of Carbon
is 12.011 grams, conversely, one mole of carbon equals the amount of
carbon atoms that weighs 12.011 grams.
Atomic weights can be found on any Periodic Table of Elements.
To determine the Molar mass of a gas, add together the atomic weights of the elements
that make up the gas.
EXAMPLE: The chemical formula for Propane is C
of propane is:
(12.011 x 2) + (1.008 x 8) = 24.022 + 8.064 =
