Under appropriate conditions, nitrogen and hydrogen undergo a combination reaction to yield ammonia: N₂ (g) + 3H₂ (g) → 2NH₃(g)
A ________ g sample of N₂ requires 3.0 g of H₂ for complete reaction.

Question

Quizplus · Accepted Answer

The molar mass of N₂ is 28 g/mol and H₂ is 2 g/mol. The reaction requires 3 moles of H₂ for every mole of N₂. Therefore, 3 g of H₂ (1.5 moles) would require 0.5 moles of N₂, which is 14 g.
