I dont really understand mole concept...
finding mole fom mass
finding mole from number of particles
mass from mole of molecule
mass from mole of atom
mass from number of particles
number of particles from mass
number of molecules from mass
number of particles from given moles

PLEASEHELP

The Mole Concept:

One mole of a substance (atoms, molecules, ions, or particles) is that quantity in number having a mass equal to its atomic or molecular mass in grams. One mole of any substance contains 6.022 � 10 23 particles (atoms, molecules, or ions). This means that one mole atom of any substance contains 6.022 �1023 atoms. Similarly, one mole molecule of any substance contains 6.022 �1023 molecules, and one mole ion of any substance contains 6.022 �1023 ions. Hence, the mass of a particular substance is fixed.

The number 6.022 � 1023 is an experimentally obtained value and is known asAvogadro’s number or Avogadro constant (represented by N o ). It is named after the Italian scientist, Amedeo Avogadro.
