How many grams of NH3 could be formed using 25.8 g of N2?

Question

Ammonia, NH₃, is commercially synthesized by the following reaction, known as the Haber process. Assuming that sufficient hydrogen is present for complete reaction, how many grams of NH₃ could be formed using 25.8 g of N₂? (atomic masses: H = 1.0, N = 14.0). Show your work. Circle your final answer. Don’t forget labels and significant figures

Answer 1

Using the balanced equation for this reaction,

N₂ + 3 H₂ → 2 NH₃

(17.0 g NH₃/1 mol NH₃) (2 mol NH₃/1 mol N₂) (1 mol N₂/ 28.0 g N₂) 25.8 g N₂ = 31.3 g NH₃
