| Zusammenfassung | We have determined Avogadro's constant NA using a direct method. The result of NA=6.0221363×1023 mol-1 differs from the most recent CODATA value of 6.0221367×1023 mol-1 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. It will be possible in the future to further reduce the uncertainties of measurement by the procedure described here. |
