How many grams of ammonia are produced from 6 moles of nitrogen?
Answer: The equation is 3H2 + N2 → 2NH3
If 6 moles of H2 gas react with N2 (assuming all reactants react)
6 * 2/3 moles of ammonia must be produced.
Therefore 4 moles of ammonia can be produced.
Since it is a gaseous equation (all reactants/products are gases), we can just assume that the Mr of the gases do not affect the amounts of the reactants or the products.
