How many octahedral voids are present in 1 mole of a compound having cubic close packed structure ?

Explanation

To determine the number of octahedral voids present in 1 mole of a compound with a cubic close-packed (CCP) structure, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure**: In a cubic close-packed (CCP) structure, also known as face-centered cubic (FCC), the arrangement of atoms creates both tetrahedral and octahedral voids.

2. **Identify the Relationship**: It is known that in a cubic close-packed structure, the number of octahedral voids is equal to the number of atoms present in the structure. Therefore, if there are 'n' atoms, there will also be 'n' octahedral voids.
