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  .

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

58750.08068 is the answer i think
