(atomic mass 
) crystallizes in a hexagonal close packed structure. The total number of voids in 
of 
is 
. (Round off to the Nearest Integer).
Text Solution
Verified by ExpertsThe correct answer is:
15
(15)
structure: Per atom, there will be one octahedral void 
and two tetrahedral voids 
. Therefore
total three voids per atom are present in 
structure.
therefore total no of atoms of Ga will be- 
Now, total Number of voids 
total no. of atoms
