Calculate the volume of unit cell if an element having molar mass 56 ~g ~mol ⁻¹ that forms bcc unit cells. [ . N _ A =4: 8 10²⁴ ~g ~cm ⁻³ ~mol ⁻¹ ]

Step-by-step solution

aligned & Density of unit cell = = M n a^3 N_A & Volume of unit cell (a^3 )= M n N_A & = 56 ~g ~mol ⁻¹ 2 4.8 10²⁴ ~g ~cm ⁻³ ~mol ⁻¹ & =2.33 10⁻²³ ~cm ^3 & aligned
