最近看到一篇文献，Wet chemical synthesis of gold nanoparticles using silver seeds: a shape control fromnanorods to hollow spherical nanoparticles，2007 Nanotechnology 18 115608），给出的计算公式怎么也算不对，请高手指点，具体该怎么计算银粒子的摩尔浓度（原文公式如附图），
其中文章说：MAg is mole concentration of Ag atoms of seed solution
(2.5 × 10−4 M); Vfcc is silver unit cell volume (fcc, a = b =c = 0.4078 nm, Vfcc = 0.0678 nm3); R is the statistical mean
radius of as-prepared silver seeds (1.665 nm, obtained from
TEM study); nfcc is the atomic number of each unit cell (4
for fcc). The calculated MS is ∼0.343 × 10−8 M.
我是怎么也计算不能得到0.343 × 10−8 M这个结果，求详细解答
