Approx. 1L of ammonia............

Explanation:

We need (i) a stoichiometric equation.....

12N2(g)+32H2(g)NH3(g)

And (ii) we need equivalent quantities of dinitrogen gas.....

1.4g28.01gmol1=0.050mol with respect to N2.

Given the equation I can make AT MOST 0.100mol with respect to ammonia........Agreed?

Since an ideal gas has a molar volume at STP of 22.4Lmol1 (or whatever your syllabus says), we gots a volume of....

22.4Lmol1×0.05mol1L
