Ammonia, nh3, can be made by reacting nitrogen and hydrogen and the equation is n2 + 3h2 --> 2nh3 how many moles of nh3 can be made if 19 moles of h2 react with enough n2? mol

You have a balanced equation that says one mole of  plus three moles of  react to produce two moles of . So if 2 moles of hydrogen are required for 3 moles of ammonia, then you can make the simplest of equations to solve this. That is,



Solving for the number of moles of hydrogen then



You were given the number of moles of ammonia so plug it in and you are done!
