Definition of Avogadro's constant in English:

Avogadro's constant

(also Avogadro's number)


  • The number of atoms or molecules in one mole of a substance, equal to 6.023 × 1023.

    • ‘Actually that's many more bits than you could register if you just stored a bit on every atom, because Avogadro's number of atoms store about 10 bits.’
    • ‘One of the most convenient is Avogadro's number, 6.022 x 10 molecules per mole.’
    • ‘Note that one mole contains Avogadro's number of atoms, which is 6. 02x10.’
    • ‘With these diatomic molecules, there is an Avogadro's number of diatomic molecules in the amount of gas that is equivalent to the relative molecular mass.’
    • ‘What it is is an impressive example of how successive dilutions can overcome a huge number, namely Avogadro's number.’
    • ‘The numerical coefficient is 3000 hc ln / (4 [pi] 2 N A ), where N A is Avogadro's constant.’
