Question

How many moles of H2 are needed to produce 18 moles NH3 in the reaction below?

N2 + 3 H2 —> 2 NH3

Answer 1

27 moles of H₂

Step-by-step explanation:

Equation of reaction:

N₂ + 3H₂ → 2NH₃

From the equation of reaction,

3 moles of H₂ is required to produce 2 moles of NH₃

3 moles H₂ = 2 moles of NH₃

X moles of H₂ = 18 moles of NH₃

X = (3 * 18) / 2

X = 27 moles of H₂

27 moles of H₂ is required to produce 18 moles of NH₃
