Answer:
V₂ = 8.8 L
Explanation:
A sample of hydrogen has a volume V₁ = 4.4 L at a pressure P₁ = 800 torr. If we decrease the pressure to P₂ = 400 torr, we can find the new volume (V₂) using Boyle's law (assuming the temperature remains constant and the gas behaves as an ideal gas).
P₁ × V₁ = P₂ × V₂
800 torr × 4.4 L = 400 torr × V₂
V₂ = 8.8 L
