Question

10. An element has a bcc structure with
unit cell edge length of 288 pm. How
many unit cells and number of atoms
are present in 200 g of the element?
(1.16x1024, 2.32x1024)​

Answer 1

For bcc unit cell, n = 2. ∴ Number of atoms in 200 g element is 1.16 × 1024. ∴ Number of unit cells in 200 g element is 5.80 ×1023.
