• At a pressure of 760 torr a balloon has a volume
  of 1.50 L. If the balloon is put into a
  container and the pressure is increased to 2500
  torr (at constant temperature), what is the new
  volume of the balloon?

3

• At a pressure of 1.5 atm a balloon has a volume
  of 3.25 L. If the pressure is decreased to 1.0
  atm (at constant temperature), what is the new
  volume of the balloon?

4

• At a temperature of 30oC, a balloon has a volume
  of 1.50 L. If the temperature is increased to
  60oC (at constant pressure), what is the new
  volume of the balloon?

5

• At a temperature of 22oC, a balloon has a volume
  of 8.0 L. If the temperature is increased to
  55oC (at constant pressure), what is the new
  volume of the balloon?

6

• At a temperature or 30oC, a gas inside a 1.50 L
  metal canister has a pressure of 760 torr. If
  the temperature is increased to 60oC (at constant
  volume), what is the new pressure of the gas?

7

• At a temperature of 75oC, a gas inside a 5.00 L
  metal canister has a pressure of 2500 torr. If
  the temperature is decreased to 45oC (at constant
  volume), what is the new pressure of the gas?

8

• A 2.0 L balloon contains 0.35 mol o f Cl2(g). At
  constant pressure and temperature, what is the
  new volume of the balloon if 0.20 mole of gas is
  removed?

9

• A 9.1 L balloon contains 1.25 mol of He(g). At
  constant pressure and temperature, what is the
  new volume of the balloon if 0.75 mol of He is
  added.

• A balloon wit a volume of 1.50 L is at a pressure
  of 760 torr and a temperature of 30oC. If the
  pressure is increased to 2500 torr and the
  temperature is raised to 60oC, what is the new
  volume of the balloon?

11

• A ballooon with a volume of 2.00 L is at a
  pressure of 1.5 atm and a temperature of 20oC.
  If the pressure is increased to 2.0 atm and the
  temperature is raised to 25oC, what is the new
  volume of the balloon?

12

• A 250 mL flask contains He at a pressure of 760
  torr and a temperature of 25oC. What mass of He
  is present?

13

• A 750 mL flask contains O2 at a pressure of 0.75
  atm and a temperature of 20oC. What mass of O2
  is present?
