a. P1 = 350 mm Hg, V1 = 200 mL, P2 = 700 mm Hg
b. P1 = 0.75 atm, V2 = 435 mL, P2 = 0.48 atm
c. V1 = 2.4 x 105 L, P2 = 180 torr, V2 = 1.8 x 103 L
6. If the pressure exerted on a 240mL sample of hydrogen gas at a constant
temperature is increased from 325 mm Hg to 550 mm Hg, what will be the
final volume of the sample?
7. A flask containing 155 cm3 of hydrogen was collected under a pressure of
22.5 kPa. What pressure would have been required in order for the volume of
the gas to have been 90.0 cm3 at constant temperature?

8. A gas has a volume of 450 mL at standard pressure. If the temperature is
held constant, what volume would the gas occupy if the pressure were
a. doubled.
b. reduced to one-fourth of its original value.
9. If a sample of oxygen that occupies 1.00 x 106 mL at 575 mm Hg is subjected
to a pressure of 1.25 what will be the final volume of the sample if the
temperature is held constant?
