Answer to Question #276601 in Chemistry for kid

Question

How many grams of NH₃ can be made from 6.58  mol of H₂ and excess N₂?

Answer 1

Solution:

Balanced chemical equation:

N₂(g) + 3H₂(g) → 2NH₃(g)

According to stoichiometry:

3 mol of H₂ produces 2 mol of NH₃

Thus, 6.58 mol of H₂ produces:

(6.58 mol H₂) × (2 mol NH₃ / 3 mol H₂) = 4.387 mol NH₃

Calculate the mass of NH₃:

The molar mass of NH₃ is 17.031 g/mol

Therefore,

(4.387 mol NH₃) × (17.031 g NH₃ / 1 mol NH₃) = 74.7 g NH₃

Answer: 74.7 grams of NH₃ can be made
