高中化学课本第一册(必修),配制一定物质的量浓度的溶液实验中,计算配制100ml2.0mol/L NaCl溶液所需NaCl固体的质量是11.7g,本人认为这个数据不太符合实际情况,其理由是:①配制溶液100ml,这样量较大;②浪费药品很多,我们学校高一有1
In the first volume (required) of high school chemistry textbooks, the amount of NaCl solids used to prepare 100 ml of 2.0 mol/L NaCl solution was determined to be 11.7 g. I think this data does not meet the actual situation. The reason is: 1 preparation solution 100ml, so that the amount is larger; 2 a lot of waste of drugs, our school has a high one
