克分子浓度

根据克分子浓度而非根据活度得到的粗略计算结果即可满足要求。

Rough calculations obtained by use of molar concentrations rather than activities are sufficient .

用CaCl2溶液饱和的应变随着盐克分子浓度的增加而减小。

The strain is reduced by saturating the sample with CaCl 2 solutions of increasing concentrations .

这两种溶液仍然含有相同数量的分子，因为它们的克分子浓度相同。

These two solutions still contain exactly the same number of molecules because they are of the same molarity .

一定要记住，讲求礼貌是非常重要的。根据克分子浓度而非根据活度得到的粗略计算结果即可满足要求。

Always remember , politeness accounts to a lot . Rough calculations obtained by use of molar concentrations rather than activities are sufficient .

在涉及溶液的物理性质如蒸汽压，冰点和沸点时，通常使用重量克分子浓度。

Molal solution are normally used when the physical properties of solutions , such as vapor pressure , freezing point and boiling point , are involved .
