Correct answer
3400
Step-by-step explanation
N2(g) + 3H2(g) 2NH3(g)
Number of moles of N2 = = 100
Number of moles of H2 = = 500
Here N2 is limiting reagent.
Number of moles of NH3 produced = 2 100 = 200
Mass of NH3 produced = 200 × 17 = 3400 gm
Number of moles of N2 = = 100
Number of moles of H2 = = 500
Here N2 is limiting reagent.
Number of moles of NH3 produced = 2 100 = 200
Mass of NH3 produced = 200 × 17 = 3400 gm
