30g N2, 90g 3H2 find ammonia

Question

If 30g of nitrogen   90g of hydrogen taken find ammonia

Answer 1

N₂(g) + 3H₂(g)==>2NH₃(g)

moles N₂ = 30 g x 1 mol/28 g = 1.07 moles N₂

moles H₂ = 90 g x 1 mol/2 g = 45 moles H₂

Limiting reactant = N₂

moles NH₃ formed = 1.07 moles N₂ x 2 moles NH₃/mole N₂ = 2.14 moles NH₃

mass NH₃ formed = 2.14 moles NH₃ x 17 g/mol = 36.4 g
