I don't know how to complete this question. I assume that you use ratios, but i don't where to start. Do you find out which reactant is in excess?
1.5 mol of ammonia was mixed with 0.60 mol of oxygen gas in a sealed vessel and allowed to react completely according to the chemical equation:
4NH3+502 ----> 4NO+6H20
After the reaction was complete, what would the total amount of gas(in mol) in the vessel be?
