Question

A compound forms a hep structure. Calculate the number of octahedral voids in 0.4 mol. (NA = 6.022 × 10²³).

Answer 1

Given: C = 0.4 mol

Number of atoms in 0 .4 mol

0.4 × N_A

= 0.4 × 6.022 × 10²³

= 2.4098 × 10²³

Number of octahedral voids

= Number of atoms

∴ Number of octahedral voids = 2.4098 × 10²³
