Vedclass · Answer

(D) The chemical formula of sodium ferrocyanide is $Na_4[Fe(CN)_6]$.Each molecule of sodium ferrocyanide contains $4$ sodium $(Na)$ atoms.Therefore,the number of $Na$ atoms in $2$ moles of sodium ferrocyanide is calculated as:Number of $Na$ atoms = (Number of moles) $	imes$ (Number of $Na$ atoms per molecule) $	imes$ (Avogadro's number)Number of $Na$ atoms = $2 	imes 4 	imes 6.022 	imes 10^{23}$Number of $Na$ atoms = $8 	imes 6.022 	imes 10^{23} \approx 48.176 	imes 10^{23} \approx 48 	imes 10^{23}$ atoms.Thus,the correct option is $(D)$.
