Boyle’s Law (P, V, constant T)

DIRECTIONS: Be sure that you show all work and use units for the problems that follow. Note: if a condition (such as temperature) is not mentioned in a problem, it is constant.

- A sample of gas occupies 523 mL at 1.00 atm. The pressure is increased to 1.97 atm. What is the new volume?

- A sample of oxygen gas has a volume of 150. mL at a pressure of 0.947 atm. What will be the volume of the gas at a pressure of 1.00 atm?

- A sample of gas in a syringe has a volume of 9.66 mL at a pressure of 64.4 kPa. The plunger is depressed until the pressure is 94.6 kPa. What will be the new volume?

- A 125 mL sample of a gas at 105 kPa has its volume reduced to 75.0 mL. What is the new pressure?

Answers 1. 265 mL 2. 142 mL 3. 6.58 mL 4. 175 kPa
