Production of ammonia is N2 + 3 H2 ----> 2 NH3. What is the max number of moles of NH3 can be produced on reaction of a mixture of 5 moles of N2 and 6 moles of H2?

A. 9
B. 10
C. 6
D. 2
E. 4

I keep getting 10 moles which is incorrect so someone please explain

1 mol of N2 is needed for every 3 mols of H2. the 6 mols of H2 is the limiting reagent. so you can make 4 mols of NH3 using 6 mols of H2.
