Ammonia, an important source of fixed nitrogen that can be metabolized by plants, is produced using the Haber process in which nitrogen and hydrogen combine.
N₂(g) + 3H₂(g) $\to$ 2NH₃(g)
How many grams of nitrogen are needed to produce 325 grams of ammonia?

Quizplus · Accepted Answer

The molar mass of NH₃ is 17 g/mol, so 325 g of NH₃ is 325/17 = 19.12 mol. From the balanced equation, 1 mol of N₂ produces 2 mol of NH₃, so 19.12 mol of NH₃ requires 19.12/2 = 9.56 mol of N₂. The molar mass of N₂ is 28 g/mol, so 9.56 mol of N₂ is 9.56 * 28 = 267 g.
