If 4 moles of N ₂ gas is mixed with 9 moles of H ₂ gas to synthesize ammonia, the maximum number of moles of NH ₃ formed is _________.

Correct answer

6

Step-by-step solution

The balanced chemical equation for the synthesis of ammonia is: N ₂ + 3 H ₂ 2 NH ₃ Given: Moles of N ₂ = 4 Moles of H ₂ = 9 To find the limiting reagent, divide the given moles by their respective stoichiometric coefficients: For N ₂ : 4 1 = 4 For H ₂ : 9 3 = 3 Since 3 From the balanced equation, 3 moles of H ₂ produce 2 moles of NH ₃ . Therefore, 9 moles of H ₂ will produce 2 3 9 = 6 moles of NH ₃ . The maximum number of moles of NH ₃ formed is 6 . Answer: 6
