摘要：

A reevaluation has been made of the density and molar mass data for the silicon single crystals used in three Avogadro projects in which the author's institutions are cooperating, A value of 12.058 825(15) cm(3) . mol(-1) at 22.5 degrees C was obtained for the ratio M(Si)/rho(Si), which is considered our present best estimate of the silicon molar volume, This implies for the Avogadro constant a value of 6.022 137 8(75) x 10(23) mol(-1), with a relative difference of (2 +/- 12) x 10(-7) with respect to the value published in [1].
