Question

Zinc forms hcp structure. What is the number of octahedral voids formed in 0.2 mol of it?

Options

• 1.2 × 10²⁴

• 2.4 × 10²³

• 1.2 × 10²³

• 2.4 × 10²⁴

Answer 1

1.2 × 10²³

Explanation:

Number of atoms in 0.2 mol = 0.2 × N_A

= 0.2 × 6.022 × 10²³

= 1.2 × 10²³

Number of octahedral voids = Number of atoms

= 1.2 × 10²³
