Final answer:
To find the amount of ammonia produced from 3.0 moles of hydrogen, we use the stoichiometry of the balanced equation N2 + 3 H2 → 2 NH3. Given the molar mass of ammonia as 17 g/mol, 2 moles of ammonia (34 grams) will be produced from the reaction of 3.0 moles of hydrogen.
Step-by-step explanation:
The question asks how many grams of ammonia (NH₃) will be produced when 3.0 moles of hydrogen (H₂) has reacted. The reaction in question is represented by the balanced chemical equation N₂ + 3 H₂ → 2 NH₃. According to stoichiometry, 3 moles of hydrogen gas would react with nitrogen gas to produce 2 moles of ammonia. Since we start with 3.0 moles of hydrogen, we can expect to form 2 moles of ammonia because of the mole ratio of hydrogen to ammonia, which is 3:2.
First, we should calculate the molar mass of ammonia. Ammonia has a molar mass of approximately 17 g/mol (14 g/mol from nitrogen and 3 g/mol from the three hydrogen atoms). Therefore, 2 moles of ammonia have a mass of 2 moles * 17 g/mol = 34 grams.
So, when 3.0 moles of hydrogen react according to the provided equation, 34 grams of ammonia will be produced.
