2.64 moles of H₂, reacting with excess N₂, produce around 29.98 grams of NH₃ according to the stoichiometry of the balanced chemical equation.
To determine the grams of ammonia (NH₃) produced from 2.64 moles of hydrogen gas (H₂) reacting with excess nitrogen (N₂), we use the stoichiometry of the balanced equation:
→
The balanced equation shows a 1:3 ratio between moles of hydrogen and moles of ammonia. Thus, for 2.64 moles of H₂, we can calculate the moles of NH₃ produced:
Moles of NH₃ = ((2.64 moles of H₂)/3)
2
Moles of NH₃
1.76
Next, we find the mass of NH₃ using its molar mass (approximately 17.03 g/mol):
Mass of NH₃ = Moles of NH₃
Molar mass of NH₃
Mass of NH₃
1.76
17.03
Mass of NH₃
29.98 grams
Therefore, from 2.64 moles of H₂ reacting with excess N₂, approximately 29.98 grams of NH₃ would be produced.
