部编全日制十年制高一化学教材中对摩尔质量给出了明确的定义,即1摩尔物质所具有的质量叫摩尔质量,单位用克/摩尔表示。但对物质微粒的摩尔质量却是根据摩尔概念用比例关系推出的。原因是1摩尔不同物质微粒含有相同的微粒(分子、原子、或离子)数,所以1摩尔不同微粒的质量之比就等于微粒的相对质量之比(分子量之比、原子量之比或离子的式量之比),按这种方法讲,学生较难接受,原因是学生对衡量物质的量的标准12克碳—12所包含的碳原子数,即6.02×10~(23)个还有待进一步深化;另外原子量与摩尔质
The Department has compiled a definitive definition of the molar mass in the full-time, 10-year, high-chemistry chemistry textbook. That is, the mass of a mole of a substance is called molar mass, and the unit is expressed in grams/mol. However, the molar mass of the material particles is based on the molar concept and the proportional relationship is introduced. The reason is that 1 mole of different substance particles contain the same number of particles (molecules, atoms, or ions), so the ratio of the mass of 1 mole of different particles is equal to the ratio of the relative mass of the particles (ratio of molecular weight, atomic weight or ion The ratio of quantity), according to this method, the students are more difficult to accept, because the student has to wait for further measures of the amount of material 12g carbon-12 contained in the standard carbon number, that is, 6.02×10~23. Deepening; additional atomic weight and molar mass
