Answer to Question #142629 in General Chemistry for Amanda Lopez

Question

How many moles of NH3 are produced when 1.3 mol of H2 reacts?

Answer 1

Solution:

A chemical equation must be balanced:

N₂ + 3H₂ = 2NH₃

         1.3   –   x

According to the reaction equation from 3 mol of H₂ be produced 2 moles of NH₃.

Therefore,

moles of NH3 = 1.3 mol H₂ × 2 mol NH₃ / 3 mol H₂ = 0.87 mol

Answer: 0.87 moles of NH₃ are produced from 1.3 moles of H₂.
