Question

formula for density of unit cell in solid state​

Answer 1

Explanation:

$\underline{\underline{\bold{\mathtt{ Unit\: cell }}}}$

Unit cell is the smallest portion of a crystal lattice which Whenever observed in a different directions generates or seems the entire lattice.

$\underline{\underline{\bold{\mathtt{Density \:of\: unit\: cell }}}}$

==] It is basically the ratio of the mass of disappears present in unit cell and the total volume of unit cell .

$\boxed{\bold{\mathsf{Density\:of\:unit\:cell = \frac{Mass\:of\:total\:atoms\:present\:in\:a\:unit\:cell}{Volume\:of\:that\:unit\:cell}}}}$

$\boxed{\bold{\mathsf{D = \frac{ZM}{N_a (a^{3} \times 10^{-30})}gcm^{-3}}}}$

where ,

Z = number of atoms in a unit cell

M = molar mass

Na = Avogadro number
