how many moles of ammonia are produced by 2.8mol of hydrogen?
3H2 + ????> 2NH3
so you get 2 moles for each 3 moles H2, so 2.8*(2/3)= xxxxx moles
To determine the number of moles of ammonia produced by a certain amount of hydrogen, we need to know the balanced chemical equation for the reaction in which ammonia is produced. Without that information, we cannot provide an accurate answer. However, I can guide you on how to solve this type of problem.
1. Write the balanced chemical equation: Determine the balanced chemical equation for the reaction in which ammonia is produced. For example:
N₂ + 3H₂ → 2NH₃
2. Identify the stoichiometry of the reaction: Examine the balanced equation to determine the ratio of moles between hydrogen (H₂) and ammonia (NH₃). In the example equation, the stoichiometry is 3:2, meaning that for every 3 moles of hydrogen, 2 moles of ammonia are produced.
3. Use stoichiometry to calculate: Now you can use the stoichiometry ratio to calculate the number of moles of ammonia produced. Divide the given number of moles of hydrogen by the stoichiometry ratio.
For example, let's assume the stoichiometry ratio is 3:2:
Number of moles of ammonia = (Number of moles of hydrogen) x (Stoichiometry ratio)
Number of moles of ammonia = 2.8 mol H₂ x (2 mol NH₃ / 3 mol H₂)
Simplifying the calculation:
Number of moles of ammonia = 2.8 mol H₂ x (2/3)
Number of moles of ammonia ≈ 1.87 mol NH₃
Remember that these calculations depend on the specific balanced chemical equation for the reaction. Be sure to use the correct equation when performing these calculations.
