物质的量被广泛地应用于农业生产和科学研究中。由物质的量的概念引出的阿伏加德罗常数、摩尔质量、气体摩尔体积、物质的量浓度等基本概念在化学中有重要应用,贯穿整个高中化学学习。一、物质的量考点归纳阿伏加德罗常数的理解、阿伏加德罗定律及其推论的应用。二、解此类题必备知识归纳1.理解物质的量、摩尔质量、气体摩尔体积、物质的量浓度等概念;记住并能熟练运用物质的量与粒子数、气体体积、物质质量、物质的量浓度之间的计算公式。
The amount of material is widely used in agricultural production and scientific research. The basic concepts of Avogadro’s number, molar masses, molar volumes of gases, and concentrations of substances, which are derived from the notion of quantity of matter, have important applications in chemistry throughout the chemistry of high schools. First, the amount of material test induction inductive Avogadro’s understanding of the application of Avogadro’s Law and its corollary. Second, the solution of such questions must-have knowledge induction 1. Understanding of the amount of material, molar mass, gas molar volume, the concentration of substances such as concepts; remember and skilled use of the amount of material and the number of particles, gas volume, material quality, The calculation of the amount of substance between the concentration of formula.
