The Following Reaction Is Investigated (Assume an Ideal Gas Mixture) $\times$

The following reaction is investigated (assume an ideal gas mixture) : 2N₂O(g) + N₂H₄(g) 3N₂(g) + 2H₂O(g)
Initially there are 0.10 moles of N₂O and 0.25 moles of N₂H₄,in a 10.0-L container.If there are 0.048 moles of N₂O at equilibrium,how many moles of N₂ are present at equilibrium?

A) 2.6 $\times$ 10^-2
B) 5.2 $\times$ 10^-2
C) 7.8 $\times$ 10^-2
D) 1.6 $\times$ 10^-1
E) none of these
