Boyle's Law Calculations Name_______________________ Hr___ 1. If a sample of gas has a volume of 100.0ml when the pressure is 50.0kPa, what is the volume when the pressure is increased to 400.0kPa, assuming temperature and number of moles is held constant? 2. What pressure would be required to take 100.0ml of a gas at 103.0kPa and squish it down to 2.00ml, assuming temperature and number of moles is held constant? 3. A gas occupies a volume of 4.50L at 760.0mmHg and a temperature of 25.0°C. What would be the new volume at 200.0mmHg assuming temperature and number of moles is held constant. 4. If the temperature and number of moles are held constant, what would be the new volume if 2.00cm3 of a gas at 3.00atm is changed to 0.0200atm? 5. Some oxygen occupies 250.ml when its pressure is 720.mmHg. How many milliliters will it occupy when its pressure is 750.mmHg assuming temperature and number of moles is held constant? 6. A gas collected when the pressure is 800.mmHg has a volume of 380.ml. What volume, in ml, will the gas occupy at standard pressure? Assume temperature and number of moles is held constant. 7. What pressure must be applied to a sample of Freon gas having a volume of 325L at 20.0°C and 723Torr to permit the expansion of the gas to a volume of 975L at 20.0°C?
