Question
Ammonia (NH3) reacts with oxygen to produce nitric oxide (NO) and water (see balanced equation below). How many grams of oxygen do you need to react with 21.4 g ammonia?
__4_NH3 + __5_O2 → __4_NO + _6__H2O
__4_NH3 + __5_O2 → __4_NO + _6__H2O

mols NH3 = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols NH3 to mols NO.
That's ?mols NH3 x (4 mols NO/4 mols NH3) = ?mols NH3 x 1/1 = ?
Then grams NO = mols NO x molar mass NO
