A) \[1.6\,\,{{N}_{A}}\]
B) 3.2
C) \[2.1\,\,{{N}_{A}}\]
D) 4.2
Correct Answer: A
Solution :
42 g of \[N_{3}^{-}\] ions have \[16\,\,{{N}_{A}}\] valence electrons 4.2 g of \[N_{3}^{-}\] ions have \[=\,\,\frac{16\,{{N}_{A}}}{42}\,\,\times \,\,4.2 = 1.6\,\,{{N}_{A}}\]You need to login to perform this action.
