Dalton's Law of Partial Pressure

What is the pressure of a mixture of nitrogen and oxygen if partial pressure of nitrogen is 594 mmHg and the partial pressure of oxygen is 165 mmHg?

What is the partial pressure of hydrogen gas in a mixture of hydrogen and helium if the total pressure is 600 mmHg and the partial pressure of helium is 439 mmHg?

Find the partial pressure of carbon dioxide in a gas mixture with a total pressure of 30.4 kPa if the partial pressures of the other two gases in the mixture are 16.5 kPa and 3.7 kPa.

What is the partial pressure of water vapor in an air sample when the total pressure is 1.00 atm, the partial pressure of nitrogen is 0.79 atm, the partial pressure of oxygen is 0.20 atm, and the partial pressure of all other gases in the air is 0.0044 atm?

Container A (with a volume 1.53 L) contains a gas under 3.24 atm of pressure. Container B (volume = 0.63 L) contains a gas under 2.99 atm of pressure. Container C (volume = 4.32 L) containes a gas under 1.21 atm of pressure. If all of these gases are put into Container D (Volume = 10.3L), what is the pressure in Container D?
