Calculate the density of metal having molar mass 210 ~g ~mol ⁻¹ that forms simple cubic unit cell. ( a ^3 N _ A =21.5 ~cm ^3 ~mol ⁻¹ )
Options
- A9.77 ~g ~cm ⁻³
- B7.15 ~g ~cm ⁻³
- C8.12 ~g ~cm ⁻³
- D6.94 ~g ~cm ⁻³
Correct answer
A. 9.77 ~g ~cm ⁻³
Step-by-step solution
For simple cubic unit cell, n =1 . Density ( )= nM a ^3 ~N _ A = 1 210 21.5 =9.77 ~g ~cm ⁻³
