33.6 \mathrm{~g} \mathrm{~N}_3^{-}

ion is

View answer and explanation

Correct option: C

12.8 \mathrm{~N}_{\mathrm{A}}

The correct answer is 12.8 NA because the total number of valence electrons in 33.6 g of N3- ion is 12.8 times Avogadro's number, calculated based on the molar mass and valence electrons of N3-.
