The equation for this step of the process should be as follows, providing us with the molar ratio of HNO3 to NO2:-
3NO2 + H2O --> 2 HNO3 + NO
We also need the molecular mass of NO2 and HNO3.
Using the mass of HNO3 , 25.2 g would be equivalent to 25.2g=0.399937 mol of HNO3.
Based on the molar ratio of HNO3 to NO2, the reaction would required 0.399937 mole = 0.599905 mole of NO2.
Using the mass of NO2, we would required 0.599905 mol = 27.6 g
