Mole concept allows counting atoms molecules and amount of substance during reaction
The present collage shows Relationship between moles, mass, number of particles and molar volume of gas.There are six lions shown in collage .Each Lion Gives one Interpretation of mole.
LION NO 1---1Mole -----in terms of particles --- = 6.023 x 1023 particles (Avogdros Number)
LION NO-2 -1Mole--------in terms of mass------1gram atom of elements—12g C
Molar mass is the mass of one mol of an element or one mol of a compound (unit in g mol-1).
LION NO 3 -1Mole--------in terms of mass------1 gram Molecule of substance----18 g H2O
Empirical formula is a chemical formula that shows the simplest whole number ratio of all atoms present in a molecule.
LION NO-4-1 Mole ------in terms of mass-----1 gram Formula weight of substance---- 58.5 g of NaCl.
Molecular formula is a formula that shows the actual number of atoms of each element in a molecule.
LION NO 5--1Mole-----in terms of volume----- = 22.4 L of a gas at STP
Middle lion: shows that mole concept in chemistry is so important the whole world celebrates mole day ie October 23rd.
Take home message
For every chemical calculation one has to go through mole
As for every decision of jungle one has to go through lion.
