A Sample of a Gas in a Cylindrical Chamber with a Movable

A sample of a gas in a cylindrical chamber with a movable piston occupied a volume of 6.414 liters when the pressure was 850 torr and the temperature was 27.2 ^°C. The pressure was readjusted to 4423 torr by moving the piston. What is the volume occupied by the sample under the new conditions if the temperature remained constant throughout?

A) 0.837 L
B) 0.937 L
C) 1.23 L
D) 1.53 L
E) 3.34 L
