A new determination of N/sub A/

Abstract

The Avogadro constant was determined by measurements of the (220) lattice spacing, density, and molar mass of silicon crystals. The measured value is N/sub A/=(6.0221379/spl plusmn/0.0000025)/spl times/10/sup 23/ mol/sup -1/.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
