Nitric acid can be produced by the reaction of

gaseous nitrogen dioxide with water.
3 NO2(g) + H2O(ℓ) −→
2 HNO3(ℓ) + NO(g)
If 900 L of NO2 gas react with water, what
volume of NO gas will be produced? Assume
the gases are measured under the same
conditions.
Answer in L.

1 answer

When dealing with gases we can use a shortcut and use L as if it were mols.
900 L NO2 x (1 mol NO/3 mols NO2) = ?
