what is mole

Answer 1

Mole (symbol: mol) is a unit of measurement in the International System of Units (SI) used to express amounts of a chemical substance. One mole is defined as the amount of the substance that contains as many elementary entities (such as atoms, molecules, or ions) as there are atoms in 12 grams of carbon-12 (which is approximately 6.02214076 × 10^23). This number is known as the Avogadro constant or Avogadro's number. The mole is used to simplify calculations in chemistry and is often used to determine the quantities of reactants and products in chemical reactions.
