Combined Gas Law

A gas has a volume of 2.50 L at 1.20 atm and 300 K.
What is the volume at 2.50 atm and 310 K?

A 5.00 L sample of oxygen is collected at 750 mmHg and 27°C.
What will the volume be at STP (1 atm, 273 K)?

A balloon filled with helium occupies 3.20 L at 25°C and 760 mmHg.
If the balloon is cooled to 0°C and the pressure increases to 800 mmHg, what is its new volume?

A scuba tank holds 12.0 L of air at 25°C and 1.05 atm.
If it is taken to a depth where the pressure is 3.25 atm and the temperature is 12°C,
what will be the new volume of air?

A weather balloon with a volume of 450.0 L is filled at 20°C and 1.00 atm.
The balloon rises until the pressure is 0.45 atm and the temperature is –25°C.
What is the new volume of the balloon?

A gas occupies 1.75 L at 98.6 kPa and 35°C.
What will the pressure be if the gas is compressed to 1.25 L at –15°C?

A sample of gas occupies 4.20 L at 1.00 atm and 27°C.
What will the volume be if the temperature is raised to 77°C and the pressure becomes 1.50 atm?

A 750 mL gas sample is collected at 740 mmHg and 298 K.
What is the volume at STP?

A gas has a pressure of 600 mmHg in a 3.00 L container at 310 K.
If the pressure is increased to 900 mmHg and the temperature is raised to 350 K, what is the new volume?

A balloon is filled with 2.50 L of air at 35°C and 0.980 atm.
What is the new volume at 0°C and 1.25 atm?
