What is the density (in g/cm3) of a fictious elemental solid which packs in a body-centered cubic unit cell with an edge length of 316 pm and a molar mass of 111 g/mol?
We know that Density,
d=( Z x atomic mass ) / ( No x a^3 x 10^-30 cm^-3 )
Where Z = No . of atoms in body centered cubic unit cell = 2
a = edge length = 316pm
No = avagadro number = 6.023x10^23
Atomic mass= molar mass= 111g/mol
Plug the values we get
d = (2*111g/mol)/(6.023*10^23*316^3*10^-30 gcm^-3)
= 11.7 g/ cm^3
