Strategy:
 According to Gay-Lussac's Law of Combining Volumes, for gaseous reactions at constant temperature and pressure, volume ratios are the same as mole ratios from the balanced equation.

Step 1: Use volume-stoichiometry
Reaction: .
Ratio of  is .

Step 2: Calculate used volume
To produce  of , the volume of  consumed is:

Step 3: Calculate remaining volume
