答案：1.(2)n(3)摩尔mol (4)n＝N/N A 2．(1)6.02×1023 mol－1 (2)N A (3)mol－1
1mol氧这种说法正确吗？如何表示1 mol氧原子、1 mol氧分子、1 mol氧离子？
提示：使用摩尔作单位时，应用化学式(符号)指明粒子的种类，1 mol氧的说法不正确，因其没有指明是氧分子、氧原子还是氧离子。1 mol氧原子、1mol氧分子、1 mol氧离子分别表示为1 mol O、1 mol O2、1 mol O2－。
答案：2.M 3.g·mol－1kg·mol－1 4．相对原子(分子)质量 5.n＝
m/M
摩尔质量与相对分子(或原子)质量相同吗？
提示：摩尔质量与相对分子(原子)质量是不同的两个概念。当质量以g作单位时二者在数值上相等，
但前者有单位，后者是相对值，可以认为单位为1，所以二者不能等同。
答案：1.数目距离大小(1)大小(2)粒子之间的距离 2．(1)温度和压强(2)L/mol L·mol－1 (3)0 ℃ 1.01×105 Pa 22.4 L/mol (4)温度压强 3．气体相同的分子数
标准状况下，1 mol气体的体积是22.4 L，当1 mol气体的体积是22.4 L时，一定是标准状
况吗？
提示：不一定，因为影响气体体积的因素是温度、压强两个条件，非标准状况下1 mol气体的体积也
可能是22.4 L。
将58.5 g NaCl溶于1 L水中，所得溶液的物质的量浓度是1 mol·L－1吗？
提示：不是，当NaCl溶于水后，溶液体积不再是1 L，故不可能是1 mol·L－1，但可以叙述为将58.5 g氯化钠溶于水得1 L溶液，则其浓度为1 mol·L－1。
答案：1.(1)100 g 质量(2)物质的量物质的量浓度 2．(1)玻璃棒(2)20.0 冷却500 2～3 胶
头滴管相切
配制480 mL、0.1 mol/L的CuSO4溶液，需称取CuSO4·5H2O的质量是多少？
提示：12.5 g。容量瓶的主要规格有100 mL、250 mL、500 mL、1 000 mL，没有480 mL的容量瓶，
要配制480 mL溶液，必须选择500 mL的容量瓶，故需称取CuSO4·5H2O的质量为：500×10－3L×0.1 mol/L
×250 g/mol＝12.5 g。

课时作业1集合及其运算 1．(2019·莱州一中模拟)已知集合A＝{x∈N|x2＋2x－3≤0}，B ＝{C|C?A}，则集合B中元素的个数为(C) A．2 B．3 C．4 D．5 解析：A＝{x∈N|(x＋3)(x－1)≤0}＝{x∈N|－3≤x≤1}＝{0,1}，共有22＝4个子集，因此集合B中元素的个数为4，选C. 2．(2018·浙江卷)已知全集U＝{1,2,3,4,5}，A＝{1,3}，则?U A＝(C) A．?B．{1,3} C．{2,4,5} D．{1,2,3,4,5} 解析：∵U＝{1,2,3,4,5}，A＝{1,3}，∴?U A＝{2,4,5}． 3．(2019·湖北四地七校联考)若集合M＝{x||x|≤1}，N＝{y|y＝x2，|x|≤1}，则(D) A．M＝N B．M?N C．M∩N＝?D．N?M 解析：因为M＝{x||x|≤1}，所以M＝{x|－1≤x≤1}，因为N＝{y|y ＝x2，|x|≤1}，所以N＝{y|0≤y≤1}，所以N?M，故选D. 4．(2019·湖南长沙长郡中学月考)已知集合A＝{0}，B＝{－1,0,1}，若A?C?B，则符合条件的集合C的个数为(C) A．1 B．2 C．4 D．8 解析：由题意得，含有元素0且是集合B的子集的集合有{0}，{0，－1}，{0,1}，{0，－1，1}，即符合条件的集合C共有4个，故选C. 5．(2014·新课标Ⅰ)已知集合A＝{x|x2－2x－3≥0}，B＝{x|－2≤x ＜2}，则A∩B＝(A)
A ．[－2，－1] B ．[－1,2) C ．[－1,1] D ．[1,2) 解析：由不等式x 2－2x －3≥0，解得x ≥3或x ≤－1，因此集合A ＝{x |x ≤－1或x ≥3}，又集合B ＝{x |－2≤x ＜2}，所以A ∩B ＝{x |－2≤x ≤－1}，故选A. 6．(2019·湖北黄冈调研)已知函数f (x )＝1 1－x 2的定义域为M ，g (x )＝ln(1－x )的定义域为N ，则M ∪(?R N )＝( A ) A ．{x |x ＞－1} B ．{x |x ≥1} C ．? D ．{x |－1＜x ＜1} 解析：依题意得M ＝{x |－1＜x ＜1}，N ＝{x |x ＜1}，?R N ＝{x |x ≥1}， 所以M ∪(?R N )＝{x |x ＞－1}． 7．(2019·广东省际名校联考)已知集合A ＝{x |x 2－x －2＜0}，B ＝{y |y ＝e x ，x ＜ln3}，则A ∪B ＝( A ) A ．(－1,3) B ．(－1,0) C ．(0,2) D ．(2,3) 解析：因为A ＝{x |－1＜x ＜2}，B ＝{y |0＜y ＜3}，所以A ∪B ＝(－ 1,3)． 8．(2019·广州质检)已知集合A ＝{x |2x 2－7x ＋3＜0}，B ＝{x ∈Z |lg x ＜1}，则阴影部分所表示的集合的元素个数为( B ) A ．1 B ．2 C ．3 D ．4 解析：∵A ＝{x |2x 2 －7x ＋3＜0}＝? ?? ?? 12，3，B ＝{x ∈Z |lg x ＜1}＝{1,2,3,4,5,6,7,8,9}，∴阴影部分表示的集合是A ∩B ＝{1,2}，有2个元
