Question

A quantity of NH3 decomposes to produce 0.0351 mol N2. How many moles of H2 are produced?

Answer 1

0.105 mol H2

Step-by-step explanation:

Answer 2

Answer is: 0,1053 moles of hydrogen are produced.
Chemical reaction: 2NH₃ → 3H₂ + N₂.
n(N₂) = 0,0351 mol..
From chemical reaction: n(N₂) : n(H₂) = 1 : 3.
n(H₂) = 3 · 0,0351 mol.
n(H₂) = 0,1053 mol.
n - amount of substance.
