Vedclass · Answer

(A) Number of atoms in $0.3 \ mol = 0.3 	imes N_A = 0.3 	imes 6.022 	imes 10^{23} = 1.8066 	imes 10^{23}$.$I$. For $hcp$ structure,the number of octahedral voids is equal to the number of atoms.Number of octahedral voids $= 1.8066 	imes 10^{23}$.$II$. For $hcp$ structure,the number of tetrahedral voids is equal to twice the number of atoms.Number of tetrahedral voids $= 2 	imes 1.8066 	imes 10^{23} = 3.6132 	imes 10^{23}$.
