Answer» Mole is the measurement in chemistry. It is used to express the amount of a chemical substance.One mole\xa0is defined as the\xa0amount of substance\xa0of a system which contains as many entities like,\xa0atoms, molecules\xa0and\xa0ions\xa0as there are atoms in\xa012 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\xa0hydrogen atoms.1 mole of hydrogen molecules represents 6.022 × 1023\xa0hydrogen molecules.1 mole of water molecules represents 6.022 × 1023\xa0water molecules. MOLE CONCEPT:- mole concept is carried out for calculation of particles ( atoms, molecules,ions) present in molecules. |
