Question

If you had 15 molecules of H2 and an unlimited supply of N2, how many

Answer 1

Answer:

10 molecules of NH₃.

Explanation:

N₂ + 3H₂ --> 2NH₃

As the N₂ supply is unlimited, what we need to do to solve this problem is convert molecules of H₂ into molecules of NH₃. To do so we use the stoichiometric coefficients of the balanced reaction:

• 15 molecules H₂ * $\frac{2moleculesNH_3}{3moleculesH_2}$ = 10 molecules NH₃

10 NH₃ molecules could be prepared from 15 molecules of H₂ and unlimited N₂.
