Recent Estimates of the Avogadro Constant

  • Richard D. Deslattes


The first microscopic information on the Avogadro constant came in 1910 (1) from the oil drop e which could be combined with the relatively well known electrochemical Faraday to obtain a value for NA. The claimed accuracy for this route ultimately reached 1000 ppm in 1916 (2).
