Mass
"Basically the total weight of something...!"
(Atomic) Mass : The mass of atoms as compared to the very special CARBON-12 ATOM in atomic mass units (u)
(Formula) Mass : The total mass of every atom in a formula of only an ionic compound in u.
(Molecular) Mass : The total mass of every atom that combine to make: a molecule of a covalent compound, a molecule of an organic compound or a polyatomic element in u.
(Molar) Mass : The mass of 1 mole (which has 6.022 x 10^23 particles) of something and is the same value (numerically of course) as atomic, formula or molecular mass but is in GRAMS PER MOLE
What is a mole anyway?
A mole, not to be confused with a small furry rodent, is a unit of measurement used for small particles with a unit conversion factor which allows for say almost weightless atoms be shown in a more manageable format.
To be precise: A mole is 6.022 x 10^23 formula units, particles, molecules or atoms of something.
Which raises the question ???
Why the random number?
Well this number... called Avogadro'a number wasn't created by Amedeo Avogadro!
THIS IS HIM! OMG! -----------------------> 
Anyway, apparently he's pretty special, for a french scientist named the number after him in 1909.
By the way...
This number is just like any ordinary way of saying there is so much of something. For instance, a dozen is a simple way of saying there is twelve of something just as a mole is a simple way of saying there is 6.022 x 10^23 of something!
See this website for super in depth information and discussion on this iconic number!
