How many moles ammonia are produced when 200 g of nitrogen reacts?

Moles of Ammonia produced : = 14.284

Given

200 grams of N₂

Required

moles of Ammonia

Solution

Reaction

N₂ + 3H₂ → 2NH₃

In chemical equations, the reaction coefficient shows the mole ratio of the reacting compound (reactants and products)

moles N₂ :

= 200 g : 28 g/mol

= 7.142

From the equation, mol ratio of N₂ : NH₃ = 1 : 2, so mol NH₃ :

=2/1 x moles N₂

= 2/1 x 7.142

= 14.284
