(D) In an $hcp$ structure,for each atom,there is $1$ octahedral void and $2$ tetrahedral voids.Number of atoms $= 0.25 \ mol 	imes 6.022 	imes 10^{23} \ atoms/mol = 1.5055 	imes 10^{23} \ atoms$.Number of octahedral voids $= 	ext{Number of atoms} = 1.5055 	imes 10^{23} \approx 1.50 	imes 10^{23}$.Number of tetrahedral voids $= 2 	imes 	ext{Number of atoms} = 2 	imes 1.5055 	imes 10^{23} = 3.011 	imes 10^{23}$.

What is the number of octahedral and tetrahedral voids present respectively in $0.25 \ mol$ of a substance having $hcp$ structure?
