The equation is as follow,

                                    N₂  +  3 H₂     →       2 NH₃

According to equation,

          67.2 L (3 mole) H₂ at STP produces  =  44.8 L (3 mole) of NH₃

So,

                            4.50 L of H₂ will produce  =  X L of NH₃

Solving for X,

                     X  =  (4.50 L × 44.8 L) ÷ 67.2 L

                     X  =  3.0 L of NH₃
