A unit cell is a term related to crystal structure. What do you mean by unit cell?

A unit cell is a term related to crystal structure. Name any two types of cubic unit cells.

Density of a unit cell is the same as the density of the substance. So, if the density of the substance is known, we can calculate the number of atoms or dimensions of the unit cell. The density of the unit cell is related to its formula mass (M), number of atoms per unit cell (z), edge length (a in cm), and Avogadro's constant N_(A) , as rho=(zxxM)/(a^(3)xxN_(A)) Q. An element X crystallizes in a structure having an fcc unit cell of an edge 100 pm. if 24 g of the element contains 24xx10^(23) atoms, the density is

A metal A (atomic mass=60) has a body-centred cubic crystal structure. the density of the metal is 4.2 g cm^(-3) . the volume of unit cell is
