A compound forms hexagonal close-packed structure. What is the total number of voids in 0.5 mol of it? How many of these are tetrahedral voids?

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Calculate the number of atoms in 0.5 moles of the compound.
To find the number of atoms in 0.5 moles, we use Avogadro's number, which is approximately \(6.022 \times 10^{23}\) atoms/mole.

\[ \text{Number of atoms} = 0.5 \, \text{moles} \times 6.022 \times 10^{23} \, \text{atoms/mole} = 3.011 \times 10^{23} \, \text{atoms} \]
