If in a CsCl crystal Cl atoms are at corners and Cs atom are located at end centre of the crystal then what will be the distance between two nearby Cs and Cl ions? Density of crystal is 3.97 gm/cm3. Molar mass of Cs and Cl is 133 and 35.5 gm/mol respectively.

Question

Chemistry Expert - askIITians · Answer

Density of crystal lattice is given by:

where, n: no of atom in unit cell
M: Molar mass of the compound
a: distance between two nearby atom
N_a: Avogadro No.

Given: Z = 3.97 gm/cm³
Molar mass = 133+35.5 = 168.5 gm/mol
N_a= 6.022 x 10²³ mole^-1
n = 2 ( for end centered cubic lattice)

On solving we get, a = 5.204 x 10^-8 cm
