The symbol 'mol' is the abbreviation of the word 'mole'. A mole is defined as that amount of a substance which contains that many amount of entities (atons, electrons, protons, etc) as that in 12 g of Carbon-12.
In essence, 1 mole of a substance contains 6.022x 10^23 entities. This number is known as 'Avagadro's number' and has the unit 'per mole' or (no.of entities/mole)
From the above definition, it becomes clear that the molecular weight of a substance refers to one mole of that substance.
The number of moles in a given sample can be calculated as-
n= mass of the sample÷molecular mass of the substance.
The concept of the mole permeates Chemistry, Chemical Technology and Chemical Engineering and is of utmost importance if you want to study science.

MOL is Mole, used in Stoichiometry. 1 Mole is equal to 6.022×10^23 Atoms. Also Hydrogen has 1.008 Atomic Mass, 1 MOL of Hydrogen equals 1.008 Grams.

MOLE!! haha 6.02x10^23
I'm taking Chemistry right now and we celebrated mole day. It's a unit of measure yes. ^^ I made a poem to go along with it haha. My teacher is a big fanatic of mole day so yes, all her students know what it is and MOL is just the short version of it....it's really dumb? i guess you can say just one letter off, but it's true.

a million mol Si * (a million mol SiF4/a million mol Si) = a million mol SiF4 a million mol F2 * (a million mol SiF4/2 mol F2) = .5 mol SiF4 you basically have adequate F2 to make .5 mol of SiF4 (proscribing reactant) (even nonetheless you have adequate Si to make a million mol - your F2 limits how lots could properly be made) so which you will basically make .5 mol SiF4.

A mole means 6.023*10^23 entities.
A mol can refer to a fixed number(which is 6.023*10^23 ) of anything
e.g. a mole of atoms,a mole of molecules, a mole of ions
It is also called AVOGADRO'S NUMBER

mol as mole for a special number of atoms or molecules
and also for molar as a unit of concentration

this letter refers to aogadro's number which is about 6.022*10^23
you can find more information in murthimer chemistry book.

MOL=MOLE
A MOLE IS A SUBSTANCE WHICH CONSISTS OF 6.23X10^23 PARTICLES.
PARTICLES=ATOMS/MOLECULES.
