what volume of ammonia gas will be produced when 1.26L of nitrogen react completely in the following equation?

N2 + 3H2 > 2NH3

Please if someone can just give me the order of operation it will be much appreciated because chemistry is just not my forte.

Just use the coefficients to tell you.
1.26 L N2 x (2 mol NH3/1 mol N2) = 1.26 x (2/1) = ?L NH3
From the equation,1L of N2 produced 2L of NH3.1.26L of N2 will produce 1.26X2/1=2.52L of NH3(Ammonia).
