Question

How many moles of NH₃ can be produced from 5.00 moles of H₂ according to the following equation? N₂ + 3 H₂ --> 2 NH₃

A. 0.67 mol
B. 2.00 mol
C. 3.33 mol
D. 7.50 mol

Answer 1

To determine the number of moles of NH3 produced from a given amount of H2, we can use stoichiometry and the molar ratio between H2 and NH3. In this case, the answer is 2.00 mol.

Step-by-step explanation:

To determine how many moles of NH₂ can be produced from 5.00 moles of H₂, we need to use the balanced equation N₂ + 3 H₂ → 2 NH₂. From the equation, we can see that the molar ratio between H₂ and NH₂ is 3:2. Therefore, for every 3 moles of H₂ consumed, 2 moles of NH₂ are produced.

Since the molar ratio between H₂ and NH₂ is 3:2, we can use stoichiometry to calculate the number of moles of NH₂ produced.

Step 1: Determine the moles of H₂ in the given amount (5.00 moles).

Step 2: Use the molar ratio (3:2) to calculate the moles of NH₂ produced.

Step 3: Convert the moles of NH₂ to the correct decimal places.

Therefore, the answer is B. 2.00 mol.
