What is common in HCP and FCC unit cell ?

The vacant space in FCC unit cell is

If the molar mass of AB is 100g "mol"^(-1) and 'a' is edge length then the density of the crystal will be for FCC cubic unit cell

Analysis OF FCC Unit Cell || Density OF Unit Cell

Length of body diagonal in FCC unit cell is alpha Å . Distance between two octahedral voids in it is:

Density of a unit cell is same as the density of the substance. If the density of the substance is known, number of atoms or dimensions of the unit cell can be calculated . The density of the unit cell is related to its mass(M), no. of atoms per unit cell (Z), edge length (a in cm) and Avogadro number N_A as : rho = (Z xx M)/(a^3 xx N_A) An element crystallizes in a structure having a fcc unit-cell an edge 100 pm. If 24 g of the element contains 24 xx 10^(23) atoms, the density is

A element cystallizes in fcc lattice and edge length of unit cell is 400 pm. If density of unit cell is 11.2 g cm^(-3) , then atomic mass of the element is
