Proportionality of reactants and products.

Question

N₂ (g) + 3H₂ (g) --> 2NH₃ (g)

Predict the mass of nitrogen needed to produce 300 g of ammonia.

Answer 1

N₂ + 3H₂ → 2NH₃

First, we need to identify the molar mass of Nitrogen and Ammonia:

1. N₂ = 28.01 g/mol
2. NH₃ = 17.03 g/mol

Then we will set up our analysis:

300 g NH3 × 1⁄17.03 NH₃ × 1 mol N₂/ 2 mol NH₃ × 28.01 N₂/1 = 246.71 g N₂

≈ 247 g N₂

Fun fact: This reaction is called the "Haber process"!
