for the reaction: 4NH3+5O2=4NO+6H2O; 15.0g of NH3 and 27.5g of O2 were reacted.
a). which is the limiting reactant?
b).how many moles of NO are formed from the limiting reactant in the above reaction.
what would be the first step in this problem?

  1. How much of this do you know how to do? Be specific. I can help you through it but I'm not inclined to work it in detail if you already know how to do some of it.

  2. i know how to do the moles but i couldn't figure out which one is the limiting reactant. to do the moles first i figured out the molecular weight for NO(30.01). but i don't understand what the mass in grams will be.
