溶液中溶质质量分数的计算是初中化学计算中的重要内容 ,学生在计算中常遇到一些题目 ,看似简单 ,实际上很容易出错。因为这些题目中常设有一些“陷阱” ,一不小心 ,便会掉下去。现分类归纳如下。一、溶质判断不正确造成的错误及改正方法1、忽略被溶物质是否会全溶而造成的错误 Solute mass fraction calculation solution is an important part of junior high school chemistry calculation, students often encounter some problems in the calculation, seemingly simple, in fact, very easy to make mistakes. Because of these problems often have some “trap”, accidentally, it will fall. Now classified as follows. First, the error caused by improper solute judgment and correction method 1, ignore the dissolved matter is completely dissolved and caused the error
