jfraser · Answer

you have the mass of a reactant, and you need to find the mass of product produced. 

convert the mass of $N_2$ into moles using molar mass

use the mole ratio from the balanced reaction to find moles of $NH_3$

convert the moles of $NH_3$ into grams using molar mass
convert the moles of $NH_3$ into volume using the molar volume ratio
