The density (in g cm ⁻³ ) of the metal which forms a cubic close packed (ccp) lattice with an axial distance (edge length) equal to 400 pm is . Use: Atomic mass of metal =105.6 amu and Avogadro's constant =6 10²³ ~mol ⁻¹

Correct answer

11

Step-by-step solution

aligned & CCP : & ( Z =4, a =400 pm , M =105.6 ~g / mol ) & Density = Z M a ^3 N _ A & = 4 105.6 (400 10⁻¹⁰ )^3 6 10²³ =11.00 ~g / cm ^3 aligned
