Vedclass · Answer

(B) The charge on one ${N^{3-}}$ ion is $3 	imes e$,where $e = 1.602 	imes 10^{-19} \, 	ext{C}$.One mole of ${N^{3-}}$ ions contains $N_A$ ions,where $N_A = 6.022 	imes 10^{23} \, 	ext{mol}^{-1}$.Total charge $Q = n 	imes z 	imes F$,where $n = 1 \, 	ext{mol}$,$z = 3$ (valency),and $F$ (Faraday's constant) $\approx 96485 \, 	ext{C/mol}$.Alternatively,$Q = 3 	imes (1.602 	imes 10^{-19} \, 	ext{C}) 	imes (6.022 	imes 10^{23} \, 	ext{mol}^{-1}) \approx 2.894 	imes 10^5 \, 	ext{C}$.

How much charge in coulombs is present on $1 \, \text{mole}$ of ${N^{3-}}$ ions?
