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:
