    You don't have to worry about converting to moles and back to liters. You need to know about Gay-Lussac's law of combining volumes. Coupled with Avogadro's law which says that the moles of gas are proportional to the volume, all we have to do is:

    2H2 (g) + O2 (g) - > 2H2O (g)

    2L ... 1L ... 2L

    7.25L ... 3.63L ... 7.25L

    The only work is dividing 7.25 by 2.
