1.

2. Hpw many number of molecules per unit cell which crystallizes in theform of face centred (monoclinic) lattice with a molecule at each lattice.

Answer»

FCC lattice has a conventional unit cell which is cubic with lattice point at corners and face centers and by specifying monotonic there is one atom at to each lattice point. There are 8 corners and six face centers one can simply count. The total no. of atoms in a unit cell to be

6+8=14
