Boyle’s Law
On a separate piece of paper, solve the following Boyle’s Law problems: 1. Convert 350.0 mL at 740.0 mm of Hg to its new volume at standard pressure. 2. 500.0 mL of a gas is collected at 745.0 mm Hg. What will the volume be at standard pressure? 3. Ammonia gas occupies a volume of 450. mL at a pressure of 720. mmHg. What volume will it occupy at standard pressure? 4. A sample of oxygen gas occupies a volume of 250. mL at 740. torr pressure. What volume will it occupy at 800. torr pressure? 5. A sample of carbon dioxide occupies a volume of 3.50 liters at 125 kPa pressure. What pressure would the gas exert if the volume was decreased to 2.00 liters? 6. A 2.0 liter container of nitrogen had a pressure of 3.2 atm. What volume would be necessary to decrease the pressure to 1.0 atm? 7. A sample of hydrogen at 1.5 atm had its pressure decreased to 0.50 atm producing a new volume of 750 mL. What was its original volume? 8. You are now wearing scuba gear and swimming under water at a depth of 66.0 m. You are breathing air at 3.00 atm and your lung volume is 10.0 L. Your scuba gauge indicates that your air supply is low so, to conserve air, you make a terrible and fatal mistake: you hold your breath while you surface. What happens to your lungs? Why?
