Question

A compound forms hexagonal close packed structure what is the total number of void in 0.5 mole of it

Answer 1

Answer:

Explanation:

Total number of atoms in hcp structure is 6.

So, number of octahedral voids=6Number of tetrahedral voids=6*2=12

So, total voids=6+12=18

Hence, number of voids=18*1/2*6*10^23=54*10^23

There are 54*10^23 voids(including both tetrahedral and octahedral voids).

Answer 2

Answer:

Total voids = 9.033×10^23 voids

Therefore, 9.033×10^23 voids will be present in 0.5 mol of compound.
