(C) The number of protons in one $NH_{4}^{+}$ ion is calculated as: $7 (N) + 4 (H) = 11$ protons.The molar mass of $NH_{4}^{+}$ is $14 + 4 	imes 1 = 18 \ g/mol$.The number of moles of $NH_{4}^{+}$ in $1.8 \ g$ is $\frac{1.8 \ g}{18 \ g/mol} = 0.1 \ mol$.The number of $NH_{4}^{+}$ ions is $0.1 	imes N_{A}$.Therefore,the total number of protons is $11 	imes 0.1 	imes N_{A} = 1.1 N_{A}$.
