Given that: 3 NO2(g) + H2O(l)  2 HNO3(aq) + NO(g), what quantity (L) of NO2 is required to
completely react 125 grams of water. Assume that the gases are at standard temperature and pressure
and hence 1.00 mole occupies 22.4 L of volume.

aaronq · Answer

this is a normal stoichiometry problem. Find the moles of water, then use the stoichiometric coefficients to find the moles of NO2. Then convert to L
