Question

3H2+ N2---> 2NH3
In a particular reaction, 6.0 moles of NH3 were produced. How many moles of H2 and how many moles of N2 were reacted to produce this amount of NH3? Is there a way to answer this with dimensional analysis?

Answer 1

well the Stoichiometric coefficient give the ratio of moles of species in the reaction

9 moles of H_2 and
3 moles of N_2 are used
to give 6 moles of NH_3
