Question
CsBr crystallises in a body centred 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 x 1023 mol-1, the density of CsBr is:
-
42.5 g/cm3
-
0.425 g/cm3
-
8.25 g/cm3
-
4.25 g/cm3
Solution
D.
4.25 g/cm3
