Following are the important formulae to solve numerical based on mole concept:
Try to remember the formulae and there use.Practice as many as problems you can for better understanding.
Important formulae of mole concept:
Mole and Gram Atomic Mass: One mole of atoms = 6.022 ×1023 atoms
= Gram atomic mass of an element
= 1 gram atom of the element
Mole and Gram Molecular Mass: One mole of molecules = 6.022 ×1023 molecules
= Gram molecular mass
= 1 gram molecule of the compound
Mole in terms of volume: One mole of a gas = 22.4 litres at S.T.P.
Moles of an element = Mass of the element
Atomic mass or GA.W
Moles of a compound = Mass of the compound
Molecular mass or GMW
Mass of one atom = Atomic Mass or GAW
6.022 × 1023
Mass of one molecule = Molecular Mass or GAW
6.022 × 1023
Number of molecules = Moles × 6.022 ×1023
Number of atoms = Moles × 6.022 ×1023
Mole and Gram Atomic Mass: One mole of atoms = 6.022 ×1023 atoms = Gram atomic mass of an element = 1 gram atom of the element
