B)2280 torr
C)800. torr
D)3820 torr
E)1270 torr

According to Boyle's Law (P1V1 = P2V2), the pressure and volume of a gas are inversely proportional at constant temperature. Using the initial conditions (P1 = 760 torr, V1 = 5.00 L) and the final volume (V2 = 3.00 L), we can solve for the new pressure (P2): P2 = (P1 * V1) / V2 = (760 torr * 5.00 L) / 3.00 L = 1270 torr.
