Calculate the density of unit cell of sodium, if the edge length of cubic structure is `4.24 A^(@)`.

Text Solution

Verified by Experts

Density `d=(ZxxM)/(a^(3)N_(0))`
Z = Number of atoms per unit cell = 2 (since Na crystallise in bcc lattice) M = Gram atomic mass of sodium = 23 g `mol^(-1)` No = Avogadro number = `6.023 xx 10^(23)` a = Edge length = 4.24 angstroms
`=1.002xx10^(3) kgm^(-3)`
