Question

If 12.0L of nitrogen gas reacts with excess hydrogen gas at the same temperature and pressure, what volume of ammonia gas is produced?

N2 + 3 H2 produces 2NH3

Answer 1

From the balanced reaction equation:

One mole of N₂ gives two moles of NH₃

One volume of N₂ gives two volumes of NH₃

V(NH₃) = 2V(N₂) $= 2 \times 12.0 = 24.0 \;L$

Answer: 24.0 L
