Calculate the volume of unit cell of an element having molar mass 63.5 ~g ~mol ⁻¹ . that forms fce structure [ N _ A =5.5 10²⁴ ~g ~cm ⁻³ ~mol ⁻¹ ]
Options
- A4.1 .02 10⁻²⁵ ~cm ^3
- B5.430 10⁻²³ ~cm ^3
- C5.014 10⁻²³ ~cm ^3
- D4.618 10⁻²³ ~cm ^3
Correct answer
D. 4.618 10⁻²³ ~cm ^3
Step-by-step solution
aligned & = n M a ^3 ~N _ A & volume of unit cell = a ^3= n M N _ A & = 4 63.5 ~g ~mol ⁻¹ 5.5 10²⁴ ~g ~cm ⁻³ ~mol ⁻¹ =4.618 10⁻²³ ~cm ^3 aligned
