用单分子膜法测定阿佛加德罗常数的许多环节——药品纯度,称量天平的精密度,溶液配制的操作,滴管每毫升的滴数,水槽面积大小和测定方法,水槽清洗的方法,滴加溶掖的操作技术等,均可影响测定的结果。特别是学生实验时,常发生测定数据不稳定,误差很大,很难得到较为准确的效果。 Many aspects of the Avogadro's number determined by the monolayer method - the purity of the drug, the precision of the weighing balance, the operation of the solution preparation, the number of drips per milliliter, the area of ​​the sump, and the method of determination, Method, drip solution tuck operation techniques, etc., can affect the determination of the results. In particular, students experiment, often occurs when the measured data is unstable, the error is very large, it is difficult to get more accurate results.
