Answer 1

Step-by-step explanation:

NH₄NO₂ = N₂ + 2H₂0

1 mole 1 mole

25 grams of N₂ = 25 / 28 moles of N₂ because molecular weight of N₂ is 28.

25/ 28 moles = .8928 moles.

from the reaction above we find that 1 mole of N₂ will be formed by 1 mole of NH₄NO₂

so .8928 moles of N₂ will require .8928 moles of NH₄NO₂ .
