摩尔在中学化学教学中是个极重要的概念。理由:一是摩尔适用范围广,包括的基本单元有分子、原子、质子、中子、电子及它们的特定组合离子等。二是化学中许多基本概念,如:气体摩尔体积、克当量、摩尔浓度、当量浓度、中和热、燃烧热、PH值、气体平均分子量等都和摩尔有关,可见摩尔是多种概念的核心。三是因为摩尔是多种计算的核心。所以加强摩尔概念的教学十分重要。一、初学时打好基础。初学者有两关:一是“物质的量”抽象,而且物质的量与物质质量的克数换算不是常数。这和以前学生学过的各种量之间换算截然不同,学生头脑中固有的习惯势力防 Moore is a very important concept in chemistry teaching in middle schools. Reasons: First, Moore has a wide range of applications. The basic units include molecules, atoms, protons, neutrons, electrons, and their specific combinations of ions. The second is many basic concepts in chemistry, such as: gas molar volume, gram equivalent, molar concentration, normal concentration, neutralization heat, heat of combustion, pH value, average molecular weight of gas, etc. are all related to the mole. It can be seen that the mole is the core of many concepts. . The third reason is that Moore is the core of many kinds of calculations. Therefore, it is very important to strengthen the teaching of the Moore concept. First, lay a good foundation for beginners. There are two levels for beginners: the first is the abstraction of “quantity of matter”, and the conversion of matter’s quantity to matter’s mass is not constant. This contrasts sharply with the amount of previous studies the student has learned, and the habits that are inherent in the student’s mind
