Determine the number of moles of NH3(g) that can be produced from the following

Question

Consider the reaction represented by the (unbalanced) equation:

N₂(g) + H₂(g)→NH₃(g)

Determine the number of moles of NH₃(g) that can be produced from the following:

1. 0.35 mol N₂(g) reacts completely with H₂(g).

Answer 1

Here’s the balanced equation: 

3H₂ + N₂ → 2NH₃

You should always balance a chemical equation before attempting any stoichiometry.

This is not a limiting reactant problem because the reactants “react completely.” Hence:

0.35 mol N₂ (2 mol NH₃ / 1 mol N₂) = 0.70 mol NH₃
