1.物质的量的单位1.1物质的量的单位表述方式物质的量的单位规定是摩尔;其中1摩尔的物质中包含微粒数目有三种表述方式:A.1摩尔的微粒数目与0.012 kg C-12中所含的碳原子数相同。B.1摩尔的微粒数目与阿伏伽德罗常数N1相同。C.1摩尔的微粒数目可用6.02×1023替代。1.2三种表述方式的特点以上三种表述方式均不是对1摩尔的微粒数目进行直接表述,而是采用以甲事物的性质去描述乙事物的方法。这里甲事物的性质必须是公知公认的已知形态;或者使用人们相对熟悉的事物去表述相对陌生的事物。
1. The substance of the amount of units 1.1 The amount of material units of representation The amount of material units of regulation is a mole; where the number of particles contained in a mole of the material there are three expressions: A.1 mole number of particles and 0.012 kg C- The number of carbon atoms contained in 12 is the same. B.1 The number of moles of particles is the same as Avogadro’s number N1. C.1 mole number of particles available 6.02 × 1023 instead. 1.2 Characteristics of the three modes of expression None of the three modes of expression is a direct representation of the number of particles per mole, but rather a method of describing the properties of a thing. The nature of a thing here must be a well-known and well-known form, or use something relatively familiar to describe relatively unfamiliar things.
