Whats the chemical equation and how much hydrazine, in grams, is need to produce 10 mol of nitrogen gas?

Question

The reaction between liquid hydrazine and liquid hydrogen peroxide is used to fuel rockets. The products are nitrogen gas and water. What's the balanced chemical equation and how much hydrazine, in grams, is needed to produce 10.0 mol of nitrogen gas?

Answer 1

Chemical formula for hydrazine = N₂H₄

Molar mass N2H4 = 32.0 g/mol

Chemical formula for hydrogen peroxide = H₂O₂

Reaction:

N₂H₄ + 2H₂O₂ ==> N₂ + 4H₂O ... balanced equation

10 mol N₂ x 1 mol N₂H₄ / mol N₂ x 32.0 g N₂H₄ / mol = 320 g N₂H₄ needed
