Calculate the volume occupied by all atoms in bcc unit cell if the volume of unit cell is 1.5 10⁻²² ~cm ^3 .
Options
- A2.40 10⁻²² ~cm ^3
- B3.51 10⁻²² ~cm ^3
- C1.56 10⁻²² ~cm ^3
- D1.02 10⁻²² ~cm ^3
Correct answer
D. 1.02 10⁻²² ~cm ^3
Step-by-step solution
BCC unit cell contains 2 particles. Hence, volume occupied by particles in bcc unit cell aligned & =2 3 a ^3 16 & = 3 a ^3 8 & =0.68 1.5 10⁻²²=1.02 10⁻²² ~cm ^3 aligned
