ChemistryDoes hydrated Copper Chloride with 20 moles of H2O make sense? Homework Statement without posting all the lab data I am just wondering if this makes sense. I calculated moles Chlorine to moles Copper as 2:1. (seems reasonable to me). Then I calculated mole ratio of water to Copper...
A new definition for the mole based on the Avogadro constant: a journey from physics to chemistry 来自 万方 喜欢 0 阅读量: 28 作者:Milton,JT M.摘要: The mole is the most recent addition to the set of base units that form the International System of Units, although its pre-cursor the ...
In recent years, the definition of mole , the unit of the amount of substance , has changed to have the base units of the International System defined by "explicit-constant" formulations. The old definition, by referring explicitly to both mass and elementary units, suggests that the mole is...
