Need help

ammonia burns in oxygen to produce water and nitrogen dioxide. if the ammonia for the above reaction is prepared by combining nitrogen and hydrogen, hoe many grams of oxygen would be requred to burn the ammonia poducEd byreacting 26.5L of hydrogen measured at 296 kelvins 99.6kPa with an excess of nitrogen
 to find moles its n=m/M (mass by molar mass) to find mass its m=nxM
 and then PV=nRT or something like that
 p=pressure, v=volume, n= moles ( i think), R=8.314, T is temerature in kelvins

I can't figure out how to do this question. can anyone explain how to do it ?

Write reactions equations first.

How many moles of hydrogen?
