1.15 A compound forms hexagonal close-packed structure. What is the total number of voids in of it? How many of these are tetrahedral voids?
Amount of compound given = 0.5 mol
We know that,
So, No. of atoms
We also know that, No. of tetrahedral voids = 2(No. of atoms in closed packing)
No. of octahedral voids = No. of atoms present in closed packing.
So, Total number of voids = No. of tetrahedral voids + No. of octahedral voids.
