Changes in Avogadro's Number over Time

Authors: Joel M Williams

ALL of the methods to determine Avogadro’s Number (N) should give the same value! x-ray crystallography has commanded the quest since the 1930's. This brief paper provides a plot of many values of N from various methods over the last century. N's reciprocal change to Planck's Constant is noted. A 'power of two' expression for Avogadro's Number provides a simple compromise between the old and currently suggested values.
