Mole Concept
Term mole was suggested by Ostwald (Latin word mole = heap)
A mole is defined as the amount of substance which contains same number of elementary particles (atoms, molecules or ions) as the number of atoms present in 12 g of carbon (C-12).
1 mol = 6.023 * 1023 atoms = one gram-atom = gram atomic mass
1 mol = 6.023 * 1023 molecules = gram molecular mass
In gaseous state at STP (T = 273 K, p = 1 atm)
Gram molecular mass = 1 mol
= 22.4 L = 6.022 * 1023 molecules
