What are you reacting it with- water?
Is it this equation?
3 NO₂ + H₂O = 2 HNO₃ + NO

Work out the atomic weight of NO₂.
That's your starting point.

Then look at this site: http://www.ausetute.com.au/massmole.html

Or if you are struggling then just follow rabbit's answer on here:

^"Work out the atomic weight of NO₂"

Sorry, I meant molar mass, but you probably realised that.

Although maybe you haven't worked out yet how to check back for/acknowledge answers.
