Calculate the density of a metal having molar mass 197 ~g ~mol ⁻¹ if it forms fcc structure. [ a ^3 N _ A =40 ~cm ^3 ~mol ⁻¹ ]
Options
- A23.5 ~g ~cm ⁻³
- B21.2 ~g ~cm ⁻³
- C17.5 ~g ~cm ⁻³
- D19.7 ~g ~cm ⁻³
Correct answer
D. 19.7 ~g ~cm ⁻³
Step-by-step solution
aligned = n M a ^3 ~N _ A & = 4 197 ~g ~mol ⁻¹ 40 ~cm ^3 ~mol ⁻¹ & =19.7 ~g ~cm ⁻³ aligned
