A) \[10\text{ }g\text{ }c{{m}^{-\,3}}\]
B) \[14.2\text{ }g\text{ }c{{m}^{-\,3}}\]
C) \[6.15\text{ }g\text{ }c{{m}^{-\,3}}\]
D) \[9.32\text{ }g\text{ }c{{m}^{-\,3}}\]
Correct Answer: C
Solution :
\[d=\frac{Z\times M}{{{a}^{3}}\times {{N}_{A}}}\] For bee structure, Z = 2 \[d=\frac{2\times 50}{6.023\times {{10}^{23}}\times {{(300\times {{10}^{-10}})}^{3}}}=6.15g\,c{{m}^{-3}}\]
