These two solutions still contain exactly the same number of molecules because they are of the same molarity. 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。
Methods: To use pharmaceutics methods of depres-sion of freezing point, solute molarity and osmotic concentration. 方法:采用药剂学中的冰点降低数据法、溶质摩尔浓度计算法和渗透浓度计算法。
Some right expressions relating to solution composition, such as mass fraction, volume fraction, mass concentration, molarity and volume ratio were introduced. 对溶液组成标度,如质量分数、体积分数、质量浓度、物质的量的浓度、体积比的正确表述也一一进行了介绍。
A contained 10 g/ 1000 ml fructose, while in SEB Glucose was used instead of fructose at the same molarity. Other components and their quantities in the two extenders remained identical. A中含10g/1000ml的果糖,B中有等摩尔浓度的葡萄糖,而没有果糖,A、B中其它成分相同。
The conditons of preparation of nanometer powders ZnO were discussed by the comparison of the change of the molarity. 在摩尔浓度变化的情况下,探讨了制备纳米级ZnO粉体的条件。
