物质的量浓度计算是中学化学的重点内容,也是中学化学教学中的难点,同时也是高考的热点内容,为帮助同学们准确深刻系统的把握物质的量浓度的计算,下面介绍本人的做法. 一、抓住公式[c(B)=n(B)/V]不放松,充分利用题中已知条件,求出n(B)、V然后利用 The concentration calculation of the substance is the key content of middle school chemistry, and it is also a difficult point in chemistry teaching in middle schools. It is also a hot content of the college entrance examination. To help students accurately and systematically grasp the calculation of the concentration of substances, the following describes my own practice. , seize the formula [c(B) = n(B)/V] does not relax, make full use of the conditions known in the question, find n(B), V then use
