量纲与单位,是每一个物理量的董要组成部份,如果舍去了单位,物理量就失去本身的意义.在化学计算中,要牵涉到许许多多的物理量,每一个物理量都有各自所代表的物理意义,因而他们都应有各自的量纲和单位.但是,在现行中学化学课本中,对某些物理量的单位却没有作出严格的规定,以致造成混乱.下面以克当量为例,谈谈化学计算中的单位问题. Dimensions and units are the components of each physical quantity. If you omit the unit, the physical quantity loses its own meaning. In the chemical calculation, there are many physical quantities to be involved. Each physical quantity has its own The physical meaning of the representatives, and therefore they should all have their own dimensions and units. However, in the current high school chemistry textbooks, there are no strict rules for certain physical quantity units, resulting in confusion. The following takes the gram equivalent as an example. Talk about the unit problem in chemical calculations.
