Question

If 28 g of N₂ is reacting with H₂ to form NH₃, what would be the mass of NH₃ that will be formed?

Answer 1

First, let's begin with an equation:

N₂ + H₂ = NH₃

Balance the equation.

N₂ + 3H₂ = 2NH₃

Now we use dimensional analysis:

28 g N₂ (1 mole/ 28.0 grams) (2 mole NH₃ / 1 mole N₂) (17.0 g NH₃/1 mole NH₃) = 34 grams
