How many moles of NH3 could Be produced from 24 grams of H2?

Answer 1

The balanced equation for the synthesis of ammonia (NH₃) is 3H₂(g) + N₂(g) ==> 2NH₃(g)

moles of H₂ used = 24 g x 1 mol/2 g = 12 moles H₂

moles of NH₃ produced = 12 moles H₂ x 2 moles NH₃/3 moles H² = 8 moles NH3 (assuming N₂ is not limiting)
