Question

How many moles of ammonia (NH3) can be produced from 6.7 mol of H2 according to the following chemical equation?

3 H2 + N2 + 2NH3
Provide the answer with 2 or more significant figures.

Answer 1

4.5 moles of NH₃

Step-by-step explanation:

Step 1: Write the balanced equation

3 H₂(g) + N₂(g) ⇒ 2 NH₃(g)

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of H₂ to NH₃ is 3:2.

Step 3: Calculate the moles of NH₃ produced from 6.7 moles of H₂

We will use the previously established molar ratio.

6.7 mol H₂ × 2 mol NH₃/3 mol H₂ = 4.5 mol NH₃
