Question

Zinc forms hcp structure. What is the number of tetrahedral voids formed in 0.3 mol of it?

पर्याय

• 1.2 × 10²³

• 1.8 × 10²³

• 2.4 × 10²³

• 3.6 × 10²³

Answer 1

3.6 × 10²³

Explanation:

Number of atoms in 0.3 mol = 0.3 × N_A

= 0.3 × 6.022 × 10²³

= 1.8 × 10²³

Number of tetrahedral voids = 2 × Number of atoms

= 2 × 1.8 × 10²³

= 3.6 × 10²³
