Abstract

Avogadro's constant N(A) has been determined using a direct method. The result of N(A) = 6.0221363 x 1.0 E23/mol differs from the most recent CODATA value of 6.0221367 x 1.0 E23/mol by only 0.07 ppm, the relative uncertainties being 1.1 ppm and 0.6 ppm, respectively. The value was derived from the determination of the lattice parameter, the density and the molar mass of a silicon single crystal. This procedure may, in the future, be used to reduce further the uncertainties of measurement.
