We can use Boyle's law which states that for a fixed amount of gas at a constant temperature, the pressure and volume of the gas are inversely proportional. Mathematically, this can be represented as P1V1 = P2V2. We can plug in the given values to solve for V2: (726 mm Hg)(474 mL) = (622 mm Hg)V2. Solving for V2, we get V2 = (726 mm Hg)(474 mL) / (622 mm Hg) ≈ 553 mL. Therefore, the answer is B.
