Answer:

Write the stoichiometric equation....and consider it...

Explanation:

#1/2N_2(g) +3/2H_2(g)stackrel"catalysis"rarrNH_3(g)#

And in your scenario you have mixed stoichiometric dihydrogen and dinitrogen, i.e. #2*mol# with respect to #N_2#, and #6*mol# with respect to #H_2#.

And so, given stoichiometric reaction (the which we assume for the reaction as written), we should get a #2*mol# quantity of ammonia.

In practice, ammonia synthesis does not enjoy such yields....however, because the product is condensable (why so?), and the reactants are largely non-condensable, a decent turnover can be achieved for this, the most important reaction performed by the chemical industry.
