Hydrazine (N2H4), a rocket fuel , reacts with oxygen to form nitrogen gas and water vapor. The reaction is represented with the equation:
N2H4(l) + O2(g) → N2(g) + 2H2O(g)

If 6 moles of hydrazine react with an excess of oxygen, how many moles of water will be produced?

1.56mol H2O


6.0mol H2O


9.0mol H2O


12.0mol H2O
