In Bragg's approach to the determination of the Avogadro constant, the measurement of silicon density as the ratio of mass to volume is an essential step. With a view to achieving a relative uncertainty of 10-7 in the determination of NA, the computation of the volumes of solid density standards manufactured in the form of optically-polished silicon balls was investigated. Apart from a negligible difference, the volume considered is that of a sphere having the same average diameter. The… CONTINUE READING
