Another component of acid rain is nitric acid, which forms when NO2 , also a pollutant, reacts with oxygen and water according to the simplified equation

4NO2(g)+O2(g)+2H2O(l) → 4HNO3(aq)

The generation of the electricity used in a medium-sized home produces about 15 kg of NO2 per year.

Assuming that there is adequate O2 and H2O , what mass of HNO3 , in kg , can form from this amount of NO2 pollutant?
