阿伏加德罗常数是定量研究分子、原子、离子等微观粒子的基本概念,是中学化学中的重点和难点,也是高考的热点.阿伏加德罗常数的正误判断,可辐射到中学化学中所有的基本概念与基本理论、元素化合物、化学实验等知识.这类题目看似考查计算能力,实则是以阿伏加德罗常数为载体,考查考生对所学知 Avogadro’s constant is a basic concept that quantitatively studies the microscopic particles such as molecule, atom, ion, etc. It is the focus and difficulty in the chemistry of middle school as well as the hot spot of the college entrance examination. Positive and false judgment of Avogadro’s constant can radiate to middle school chemistry In all the basic concepts and basic theory, elemental compounds, chemical experiments and other knowledge.This kind of question may seem to test the computing power, but in fact Avogadro’s constant as a carrier to examine the candidates learned
