How many total voids are present in 1 mole of compound that forms hcp structure?

  1. A \(1.806 \times 10^{24}\)
  2. B \(1.204 \times 10^{24}\)
  3. C \(3.011 \times 10^{23}\)
  4. D \(6.022 \times 10^{23}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(1.806 \times 10^{24}\)

Step-by-step Solution

Detailed explanation

In HCP structure
For each atom total three voids are present (one octahedral and two tetrahedral) Number of atoms in \(1 \mathrm{~mol}\) of compound \(=6.022 \times 10^{23}\)
Total number of voids \(=\) No. of atoms \(\times 3\)
\(
\begin{aligned}
& =6.022 \times 10^{23} \times 23 \\
& =18.06 \times 10^{23} \\
& =1.806 \times 10^{24}
\end{aligned}
