Calculate the molar mass of metal having density 9.3 ~g ~cm ⁻³ that forms simple cubic unit cell. [ a ^3 N _ A =22.6 ~cm ^3 ~mol ⁻¹ ]
Options
- A210.2 ~g ~mol ⁻¹
- B105.3 ~g ~mol ⁻¹
- C52.6 ~g ~mol ⁻¹
- D70.2 ~g ~mol ⁻¹
Correct answer
A. 210.2 ~g ~mol ⁻¹
Step-by-step solution
For simple cubic unit cell, n =1 . Density ( )= M n a^3 N_A aligned & 9.3= M 1 22.6 & M = 9.3 22.6 1 =210.2 ~g ~mol ⁻¹ aligned
