    en.wikipedia.org/wiki/Avogadro_constant

    The Avogadro constant, commonly denoted N A [1] or L, [2] is an SI defining constant with an exact value of 6.022 140 76 × 10 23 mol −1 (reciprocal moles). [3] [4] It is defined as the number of constituent particles (usually molecules, atoms, ions, or ion pairs) per mole and used as a normalization factor in the amount of substance in a sample.

  3. Einstein (unit) - Wikipedia

    en.wikipedia.org/wiki/Einstein_(unit)

    The einstein (symbol E) is an obsolete unit with two conflicting definitions. It was originally defined as the energy in one mole of photons (6.022 × 1023 photons). [1][2] Because energy is inversely proportional to wavelength, the unit is frequency dependent. This unit is not part of the International System of Units (SI) and is redundant ...

  4. 23 (number) - Wikipedia

    en.wikipedia.org/wiki/23_(number)

    The sum of the first nine primes up to 23 is a square: + + + = = and the sum of the first 23 primes is 874, which is divisible by 23, a property shared by few other numbers. [ 7 ] [ 8 ] It is the fifth factorial prime , [ 9 ] and since 14! + 1 is a multiple of 23, but 23 is not one more than a multiple of 14 , 23 is the first Pillai prime .
