Question

Which is the number of atoms in 12.08 × 10²³ unit cells if an element crystallizes in bcc structure?

विकल्प

• 4.838 × 10²⁴

• 2.416 × 10²⁴

• 2.08 × 10²²

• 1.208 × 10²³

Answer 1

2.416 × 10²⁴ 

Explanation:

In bcc, each unit cell has 2 atoms.

No. of unit cells = `"No. of atoms"/"No. of atoms per unit cell"`

`12.08 xx 10^23 = "No. of atoms"/2`

24.16 × 10²³ = No. of atoms = 2.416 × 10²⁴
