题型一 :根据概念求相对原子质量解法 :此类型题应根据相对原子质量的概念来求解。即以一个碳 12原子的质量的 1/ 12作为标准 ,其他原子的质量跟它比较所得的值 ,就是这种原子的相对原子质量。例 :一个碳 12原子的质量为ｍｋｇ ,某元素一个原子的质量为ｎｋｇ ,则该元素的相对
Problem Type One: Find Relative Atomic Mass Solution According to Concept: This type of problem should be solved according to the concept of relative atomic mass. That is to say, a 1/12 of the mass of a carbon atom is used as a standard, and the value of the other atom’s mass is the relative atomic mass of this atom. Example: The mass of a carbon 12 atom is mkg, the mass of an atom of a certain element is nkg, then the relative of the element
