在高中化学课本里,给摩尔下的定义是: “摩尔是表示物质的量的单位,某物质如果含有阿佛加德罗常数个微粒,这种物质的量就是1摩尔”(全日制十年制学校高中化学第一册第二章第一节)。 中学生如果事先未做过测定阿佛加德罗常数的实验,或测定的值结果不正确(数值在5×10~(23)～7×10~23范围以外),往往不能理解这常数 In high school chemistry textbooks, the definition of Moore is: “Moore is a unit of quantity of matter, and if a substance contains Avocado constant particles, the amount of this substance is 1 mole” (Full-time decade High school chemistry chemistry school first chapter second chapter first section). Middle school students cannot understand this constant if they have not conducted an experiment to determine the Avogadro constant, or if the measured value is not correct (the value is outside the range of 5×10 23 to 7×10 23).
