Ammonia reacts with O2 to form either NO or NO2 according to the unbalanced equations shown below: NH3 + O2 → NO + H2O NH3 + O2 → NO2 + H2O In an experiment, 10 mol NH3 and 15.1 mol O2 are intially placed in a closed flask. After the reaction all the NH3 has reacted and 2.4 mol O2 remain. Calculate the number of moles of NO in the flask after reaction. Round your answer to two significant figures.
