If 5.8 moles of nitrogen monoxide (NO) react with 10.0 moles of oxygen gas (O2), how many moles of the product can be formed and how many moles of the excess reactant will be left over when the reaction is complete? Show all of your work.

unbalanced equation: NO + O2 NO2

First, balance your equation. Then write down what the question has given you, I find this helps. You should also note the molar ratio, this helps determine the excess. Then you can use n=m/M (the slash meaning divide).
You can change around this formula depending on the information you have and need. You should use first m=nM 
also, is that the correct equation?
