उत्तर

A compound forms hcp structure. Number of octahedral and tetrahedral voids in 0.5 mole of substance is respectively `bb(underline(3.011 xx 10^23, 6.022 xx 10^23))`.

Explanation:

No. of atoms in 0.5 mol = 0.5 × 6.022 × 1023

= 3.011 × 1023 atoms

No. of octahedral = No. of atoms

Voids = 3.011 × 1023

No. of tetrahedral voids = 2 × No. of atoms

= 2 × 3.011 × 1023

= 6.022 × 1023
