Well, you have to figure the amount of moles of each you have.
molesN2=15/28
molesH2=15/2
so you have molN2=.538
and you must have three times that H3, or 1.61 moles. Well, you have too much H2, so all doesn't react.
moles ammonia you get is then 2*.538, convert that to grams.
molesN2=15/28
molesH2=15/2
