在有关分子量、当量、摩尔、气体的摩尔体积的综合计算中,有些题目头绪纷繁,如果不抓住中心,不但浪费时间,而且容易混淆,使计算错误。在这些有关的基本计算里,中心在抓住摩尔数的计算。摩尔概念从微观角度揭示了化学反应中的数与量的关系,并使微观计量和宏观计量建立了联系,在有关质量、体积、微粒数和克当量数的计算中处于一个枢纽的地位。算出了物质的摩尔数,则物质的质量、微粒数、克当量数、气体的体积也就迎刃而解。它们相互间的关系如下:
In the comprehensive calculation of the molecular weight, the equivalent, the mole, and the molar volume of the gas, there are many problems. If you do not grasp the center, you will not only waste time, but also be confusing and make the calculation wrong. In these related basic calculations, the center is seizing the calculation of the number of moles. The Moore concept reveals the relationship between quantity and quantity in chemical reactions from a microscopic point of view, and establishes a link between micro-measurement and macro-measurement, and is at a pivotal position in the calculation of mass, volume, number of particles, and gram equivalent. When the number of moles of matter is calculated, the mass of matter, the number of particles, the number of gram equivalents, and the volume of gas are solved. Their relationship with each other is as follows:
