A) \[0.425\text{ }g/c{{m}^{3}}\]
B) \[8.5g/c{{m}^{3}}\]
C) \[4.25\text{ }g/c{{m}^{3}}\]
D) \[82.5\text{ }g/c{{m}^{3}}\]
Correct Answer: B
Solution :
[b] For body centred cubic lattice Z = 2 Atomic mass of unit cell \[=133+80=213\] a.m.u Volume of cell \[={{\left( 436.6\times {{10}^{-10}} \right)}^{3}}c{{m}^{3}}\] Density, \[\rho =\frac{ZM}{{{a}^{3}}{{N}_{A}}}\] \[=\frac{2\times 213}{{{\left( 436.6\times {{10}^{-10}} \right)}^{3}}\times 6.02\times {{10}^{23}}}\] \[=8.50g/c{{m}^{3}}\]You need to login to perform this action.
