摘要
溶液浓度的计算是中学化学教学的重要内容之一，它包括了溶液的物质的量浓度、质量分数等计算，同一物质的不同浓度溶液混合后浓度的计算又是常见的题型。为了使学生快速掌握此类习题的计算方法，本文通过相关的例题，找出了此类问题的解题要领。
The calculation of solution concentration is an important part in middle school chemistry teaching. It includes the calculation of amount-of-substance concentration, mass fraction, etc. The calculation of mixed concentration for the same substance after different concentration mixing is a common problem. In this paper, the problem solving key in this problem is found out through relevant examples in order to make students master fast speed solving method for this kind of problem.
