3NO2(g) + H2O(l) = 2HNO3(aq) + NO(g) a) How many moles of nitrogen dioxide (NO2) react completely with 4 moles of water (H2O) ?

Ive been stuck on this for a good while already.. I just can’t seem to even comprehend what it is asking me... So any help would be greatly appreciated !

3NO₂(g) + H₂O(l) → 2HNO₃(aq) + NO(g)
Mole ratio NO₂ : H₂O = 3 : 1
No. of moles of H₂O reacted = 4 mol
No. of moles of NO₂ needed = (4 mol) × 3 = 12 mol
Mole ratio NO₂ : H₂O = 3 : 1
No. of moles of H₂O reacted = 4 mol
No. of moles of NO₂ needed = (4 mol) × 3 = 12 mol
