Avogadro's number definition, the constant, 6.022 Ã 10 23 , representing the number of atoms, molecules, or ions in one mole of a substance. Symbol: N. See more.
Avogadroâs number, the number of particles in a mole, is most reliably determined by X-ray diffraction of crystals. In 1986, based on studies of silicon crystals, the number was deï¬ned as 6.0221367 x 1023. At the beginning of this century, scientists devised ingenious methods to try to estimate the size of the number.
