If you want 44.8 Liters of NH3 to be produced from the reaction below, then how many grams of N2 gas should you start with? There is excess hydrogen (H2) gas provided for the reaction.
N2 + 3H2  2NH3
Density of NH3 gas at STP is --- 0.761 g / L
Molar mass of NH3 is --- 17.04 g / mol
Molar mass of N2 is --- 28.02 g / mol
