A) 2.4 \[{{N}_{A}}\]
B) 4.2 \[{{N}_{A}}\]
C) \[1.6\,{{N}_{A}}\]
D) \[3.2\,{{N}_{A}}\]
Correct Answer: A
Solution :
14 gm \[{{N}^{3-}}\]ions have \[=8{{N}_{A}}\] valence electrons 4.2gm of \[{{N}^{3-}}\] ions have \[=\frac{8{{N}_{A}}\times 4.2}{14}=2.4{{N}_{A}}\]You need to login to perform this action.
