Define with example:atom,molecules, Avogadro's number,molar mass, chemical energy
Answers
Explanation:
The mole designates an extremely large number of units, 6.02214076 × 1023. This number was chosen in 2018 by the General Conference on Weights and Measures to be the definition of the mole 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. (See Avogadro’s law.)
