Answer:

Number of A atoms in that sample is\frac{N}{2}.

Explanation:

Number of of atoms of A in CCP ,n= 1

Number of tetrahedral voids in CCP = 2n

n = total numbers of spheres in a crystal.

Number of voids= 2 × 1 = 2

Number of B atoms in single crystal = 2

if number N numbers of B atoms are present in the sample

Then numbers of A atoms present will be:

2n=N

n=\frac{N}{2}
