问答题 Arrange the following compounds in order of increasing molar conduc tivity:(a) K[Co(NH3)2(NO2)4]  (b)[Cr(NH3)3(NO2)3]
   (c) [Cr(NH3)5(NO2)]3[Co(NO2)]2  (d)Mg[Cr(NH3)(NO2)5]
【正确答案】The larger the number of ions and the larger the charge on each, the larger the conductivity. The compounds, from lowest conducting to high est,are b＜a＜d＜c.
