How many liters of NH3, at STP, will react with 19.5 g O2 to form NO and H2O? You must show all of your work to receive credit.
4NH3(g) +5O2(g) --> 4NO(g) + 6H2O(g)
4NH3(g) +5O2(g) --> 4NO(g) + 6H2O(g)

How many mols O2 do you have in 19.5 g? That's mols = g/molar mass = ?
The equation tells you that 4 mols NH3 will react with 5 mols O2. So your ? mols O2 will need x mols NH3. x = ?
Now convert x mols NH3 to L NH3 @ STP remembering that 1 mol of a gas will occupy 22.4 L @ STP. Post your work if you get stuck.
