Answer 1

N2t3 H2 2 NH3 1 2 mass Here, moles of N = 0. 0357 mo Mo/9r masS Moles of H mass Molar MaM O.216 o.o mo) 2 1mol Nou, byvn, 1 mol N react uith 3 mol H2 /

0.D357 Mo/ N^ react ith (2x0.0259)m H2 0./07 Mol H2 So, N2 is 1fmitina reactant thon, 1mol N2 produces mos NH3 0.035 mo N2 produce= (2x0.0357)mol NH3 - 0.071 mol NH3 Nuw, mas s moles x molar mass of NH3 -214 of NH3
