《普通高中化学课程标准(实验)》将“物质的量及其相关内容”归入“认识化学科学”这一主题中,要求学生“认识摩尔是物质的量的基本单位,能用于进行简单的化学计算,体会定量研究的方法对研究和学习化学的重要作用”。从学科知识体系来看,物质的量作为国际单位制中的一个基本物理量,据其可以导出摩尔质量、气体摩尔体积、物质的量浓度等基本概念,这些概念被广泛地应用于生产、生活中,是高中生提高化学科学素质所必备的基础知识之一。物质的量等知识的学习对 “Ordinary High School Chemistry Curriculum Standards (Experiment)” classifies “substance quantity and its related content” into “knowledge chemistry science ”, and ask students to “know that Moore is the basic unit of material quantity,” Can be used to perform simple chemical calculations and realize the important role of quantitative research methods in research and learning chemistry." From the perspective of the subject knowledge system, the amount of matter serves as a basic physical quantity in the international system of units, from which basic concepts such as molar mass, gas molar volume, and substance concentration can be derived. These concepts are widely used in production and life. It is one of the basic knowledge necessary for high school students to improve the quality of chemical science. The amount of knowledge such as material
