Question

In a 1 m solution of n2h4(aq), identify the relative molar amounts of these species.

Answer 1

The question needs: 

In a 1 M solution of N₂H₄(aq), identify the relative molar amounts of these species. from most to least...

H₂O N₂H₅⁺~OH⁻ H₃O⁺ N₂H₄

H₂O is most

second N₂H₄

N₂H₅ and OH⁻ present in equal amount

H₃O⁺ is zero

because N₂H₄ is weak base it partially ionizes in water as following:

N₂H₄ + H₂O ⇄ N₂H₅⁺ + OH⁻
