11.46 grams


Consider the balanced chemical equation, which we need to obtain the molar ratios:

#3NO_2+H_2O -> NO + 2HNO_3#

I see you would like to know the grams #NO_2# required to react with your amount of atoms #NO#.

Let's use the molar ratios to calculate the amount of nitrogen dioxide required.

Consider the graphic below:
