How many total voids are present in 1 mole of compound that forms hcp structure?
Options
- A1.806 10²⁴
- B1.204 10²⁴
- C3.011 10²³
- D6.022 10²³
Correct answer
A. 1.806 10²⁴
Step-by-step solution
In HCP structure For each atom total three voids are present (one octahedral and two tetrahedral) Number of atoms in 1 ~mol of compound =6.022 10²³ Total number of voids = No. of atoms 3 aligned & =6.022 10²³ 23 & =18.06 10²³ & =1.806 10²⁴ aligned
