To solve the problem, we can use the equation P₁V₁ = P₂V₂ where P₁ and V₁ are the initial pressure and volume, and P₂ and V₂ are the final pressure and volume. Plugging in the given values, we get:
726 mm Hg × 474 mL = 622 mm Hg × V₂
V₂ = (726 mm Hg × 474 mL)/622 mm Hg
V₂ = 553 mL, which is closest to answer choice B. Therefore, the correct answer is B.
