Answer:
Explanation:
A atoms at corners(no.of corners in cube=8) and an atom A from one of the corner is missing.So,
8-1=7 corners
Contribution of corner=1/8
No.of atoms of A=7×1/8
B occupies face centers.
So, no.of faces=6
Contribution of face=1/2
No.of atoms of B=6×1/2
Now, by simplifying the above cases we get answer as A7B24
