The outermost shell of every element
WebbA mole of any substance is 6.022×1023 molecules. The Mole concept is one of the most convenient ways of expressing the amount of reactants and products in the reaction. The value of Avogadro’s number is approximately 6.022×1023. The definition of Avogadro’s number is that it tells us the number of particles in 1 mole (or mol) of a substance.
