2014届高考化学一轮复习单元课时测练 1.2阿伏加德罗常数及其应用(广东省专用) Word版含解析

2014届高三化学一轮复习训练1阿伏加德罗常数及其应用基础题1．(2013年泰州模拟)用N A 表示阿伏加德罗常数的数值，下列说法正确的是( )A ．1 mol Na 2O 2晶体中共含有4N A 个离子B ．常温常压下16 g O 2和O 3混合气体含有N A 个氧原子C ．0.1 mol AlCl 3完全水解转化为氢氧化铝胶体，生成0.1N A 个胶粒D ．17 g 的氢氧根离子中含有的电子数为9N A解析：1 mol Na 2O 2中含有2N A 个Na ＋和N A 个O 2－2离子，即离子总数为3N A ，A 不正确；B 正确；Al(OH)3胶粒由大量Al(OH)3聚集而成，故0.1 mol AlCl 3水解生成的胶粒数远远小于0.1N A ，C 不正确；1个OH －有10个电子，17 g OH －(1 mol)含有电子数为10N A 。

答案：B2．同温同压下，等体积的两容器内分别充满由14N 、13C 、18O 三种原子构成的一氧化氮和一氧化碳，两容器含有的( )A ．分子数和气体质量均不同B ．分子数和电子数均相同C ．质子数和中子数均相同D ．分子数、原子数和中子数均相同解析：同温同压、同体积的14N 18O 和13C 18O ，分子数相同，质子数和电子数不同，但中子数相同。

答案：D3．在两个密闭容器中，分别充有质量相等的甲、乙两种气体，它们的温度和密度均相同。

试根据甲、乙的摩尔质量(M )的关系，判断下列说法中正确的是( )A ．若M (甲)<M (乙)，则分子数：甲<乙B ．若M (甲)>M (乙)，则气体摩尔体积：甲<乙C ．若M (甲)<M (乙)，则气体的压强：甲>乙D ．若M (甲)>M (乙)，则气体体积：甲<乙解析：本题主要是对阿伏加德罗定律的考查，意在考查学生对气体物质的量与气体体积之间相互关系的理解。

根据题给条件，列出相关比例关系有助于准确答题。
