Vedclass · Answer

(C) The chemical formula for sodium ferrocyanide is $Na_4[Fe(CN)_6]$.Each molecule of $Na_4[Fe(CN)_6]$ contains $4$ sodium ions $(Na^+)$.Therefore, $1 \ mol$ of $Na_4[Fe(CN)_6]$ contains $4 \ mol$ of $Na^+$ ions.For $0.5 \ mol$ of $Na_4[Fe(CN)_6]$, the number of moles of $Na^+$ ions is $0.5 	imes 4 = 2 \ mol$.The number of $Na^+$ ions is calculated as $2 	imes N_A$, where $N_A \approx 6.022 	imes 10^{23} \ mol^{-1}$.Number of ions $= 2 	imes 6.022 	imes 10^{23} = 12.044 	imes 10^{23} \approx 12 	imes 10^{23}$.
