Chemistry - Solid State Question with Solution | TestHub

Given that, Mass of single Ag-atom $=m$ Unit cell length $=a$ Total atoms present per unit cell of fcc lattice $=4$ Therefore, mass of unit cell becomes $4\mathrm{m}$. Volume of unit cell $=a^3$ Density $(\rho )=\frac{\text{ Mass of unit cell }}{\text{ Volume of unit cell }}=\frac{4\mathrm{m}}{{\mathrm{a}}^3}$
