Nitrogen gas can be prepared by passing gaseous ammonia over solid copper (II) oxide at high temperatures. If 18.1 g of NH3 is reacted with 90.4 g of CuO, which is the limiting reactant? How many grams of N2 will be formed? Explain how you solved for your answers. Unbalanced equation: NH3 + CuO = N2(g) + Cu + H2O

What is the number of moles in 15.0 g ash3?
