Friends, please explain me Mole Concept...

Answer 1

Mole is the measurement in chemistry. It is used to express the amount of a chemical substance. One mole is defined as the amount of substance of a system which contains as many entities like, atoms, molecules and ions as there are atoms in 12 grams of carbon - 12". Avogadro number: The number of the particles present in one mole of any substance = 6.022x1023. This is called avogadro’s number or Avogadro’s constant. No. Of particles in 1 mole: 1 mole of hydrogen atoms represents 6.022 × 1023 hydrogen atoms. 1 mole of hydrogen molecules represents 6.022 × 1023 hydrogen molecules. 1 mole of water molecules represents 6.022 × 1023 water molecules.
