A) \[3.011\times {{10}^{23}}\]
B) \[6.022\times {{10}^{23}}\]
C) \[9.033\times {{10}^{23}}\]
D) \[1.802\times {{10}^{24}}\]
Correct Answer: C
Solution :
| Total number of voids = Number of octahedral voids + Number of tetrahedral voids. |
| Number of octahedral voids = Total number of atoms (N) is a closed structure (0.5 mol) |
| \[=0.5\times 6.022\times {{10}^{23}}\]\[=3.011\times {{10}^{23}}\] |
| Number of tetrahedral voids = 2N \[=2\times 3.011\times {{10}^{23}}=6.022\times {{10}^{23}}\] |
| Total number of voids \[=3.011\times {{10}^{23}}+6.022\times {{10}^{23}}\]\[=9.033\times {{10}^{23}}\] |
