Answer:

Mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.

The mole designates an extremely large number of units, 6.02214076 × 1023. The General Conference on Weights and Measures defined the mole as this number for the International System of Units (SI) effective from May 20, 2019. The mole was previously defined as the number of atoms determined experimentally to be found in 12 grams of carbon-12. The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s constant, in honour of the Italian physicist Amedeo Avogadro (1776–1856). Avogadro proposed that equal volumes of gases under the same conditions contain the same number of molecules, a hypothesis that proved useful in determining atomic and molecular weights and which led to the concept of the mole

The concept of the mole helps to put quantitative information about what happens in a chemical equation on a macroscopic level. For example, in the chemical reaction 2H2O → O2 + 2H2, two moles of water are decomposed into two moles of molecular hydrogen and one mole of molecular oxygen. The mole can be used to determine the simplest formula of a compound and to calculate the quantities involved in chemical reactions. When dealing with reactions that take place in solutions, the related concept of molarity is useful. Molarity (M) is defined as the number of moles of a solute in a litre of solution.

The mole is the unit of measurement for amount of substance in the International System of Units. A mole of a substance or a mole of particles is defined as containing exactly 6.02214076×10²³ particles, which may be atoms, molecules, ions, or electrons....

isme confuse hone ki koi baat nhi hai mate....

ek mole us quality ko kahte hai jisme 6.022×10²³particles(atoms or molecules) hote hai.....
