Calculate the density of an element having molar mass 63 ~g ~mol ⁻¹ that forms FCC structure [ a ^3 N _ A =28 ~cm ^3 ~mol ⁻¹ ]
Options
- A6.0 ~g ~cm ⁻³
- B9.0 ~g ~cm ⁻³
- C5.0 ~g ~cm ⁻³
- D7.0 ~g ~cm ⁻³
Correct answer
B. 9.0 ~g ~cm ⁻³
Step-by-step solution
For FCC lattice, n=4 = M n a ^3 N _ A = 63 ~g ~mol ⁻¹ 4 28 ~cm ^3 ~mol ⁻¹ =9.0 ~g ~cm ⁻³
