Find the void volume of bec unit cell in cm ^3 if volume of unit cell is 1.5 10⁻²² ~cm ^3 .
Options
- A4.8 10⁻²³
- B3.6 10⁻²³
- C2.4 10⁻²³
- D1.2 10⁻²³
Correct answer
A. 4.8 10⁻²³
Step-by-step solution
Volume of unit cell = a ^3=1.5 10⁻²² ~cm ^3 Void volume of bec unit cell =0.32 1.5 10⁻²² ~cm ^3=4.8 10⁻²³ ~cm ^3 ( Percentage of void volume in bec unit cell =32 % )
