Vedclass · Answer

(B) $1 \, mol$ of $N^{3-}$ ions contains $10 \, mol$ of electrons $(7 + 3 = 10)$.$1 \, mol$ of $O^{2-}$ ions contains $10 \, mol$ of electrons $(8 + 2 = 10)$,which equals $10 	imes 6.023 	imes 10^{23} = 6.023 	imes 10^{24}$ electrons.Option $B$ states $6.023 	imes 10^{22}$ electrons,which is incorrect.$1 \, mol$ of $CH_4$ contains $(6 + 4 	imes 1) = 10 \, mol$ of protons.$1 \, mol$ of $H_2O$ contains $(2 	imes 1 + 8) = 10 \, mol$ of protons.
