In the production of ammonia via the Habe

If you were to use 25 moles of zinc in this experiment, how many moles of hydrogen gas would be produced?In the production of ammonia via the Haber process, nitrogen gas is combined with hydrogen gas according to the following reaction: N2(g) + 3H2(g) -> 2NH3(g)If 50 moles of nitrogen gas were used in the reaction (and there was excess hydrogen gas), how many moles of ammonia could be generated
