CsBr crystallises in a body centered cubic lattice. The unit cell length is 436.6 pm. Given that the atomic mass of Cs = 133 and that of Br = 80 amu and Avogadro number being

6.02\times10^{23}\ \text{mol}^{-1}

, the density of CsBr is

Multiple Choice Options

A $4.25\ \text{g/cm}^3$
B $42.5\ \text{g/cm}^3$
C $0.425\ \text{g/cm}^3$
D $8.25\ \text{g/cm}^3$

Step-by-Step Verified Solution

Density of CsBr = Z _ M V _ N A = 1 _ 213 ( 436.6 _ 10 _ 10 ) 3 _ 6.023 _ 10 23 = 4.25 g/cm 3
