为什么科学家关心它
The mole and Avogadro constant is part of the shared Mendeleev scientific core. This page is intentionally conservative until more native-language terminology is verified.
一个具体例子
0.50 mol contains 3.01107038 × 10^23 specified entities because the Avogadro constant is exact.
值得注意
当一个定义与可测量或可观察的现象连接起来时，科学才真正容易记住。
