Gas Formulas

A beach ball is inflated with 3.25 moles of gas at a pressure of 1.81 atm.

The gas fills a volume of 16.05 liters. What is the temperature of the gas?

• pv=nrt

• P1V1/T1=P2V2/T2

• PT=P1+P2+P3.....

If I have an unknown quantity of gas held at a temperature of 1195 K in a container with a volume of 25 liters and a pressure of 4.06 atm, how many moles of gas do I have?

• PV=nRT

• P1V1/T1=P2V2/T2

• PT=P1+P2+P3......

An airtight canister is filled with four gases: oxygen, nitrogen, hydrogen, and helium. The

oxygen, nitrogen, and helium have partial pressures of 552 mmHg, 300 mmHg, and

760 mmHg. If the total pressure is 1900 mmHg, what is the partial pressure of hydrogen?

• PV=nrt

• P1V1/T2=P2V2/T2

• PT=P1+P2+P3......

A scientist obtains a flask of oxygen gas with a temperature of 314 K and a volume of

exactly 100 liters. If the flask contains 88 moles of gas, what is the pressure?

• PV=nRT

• P1V1/T1=P2V2/T2

• PT=P1+P2+P3.....

1. A gas balloon has a volume of 106.0 liters when the temperature is 45.0 °C and the pressure is 740.0 mm of mercury. What will its volume be at 20.0 °C and 1.2 atm pressure?

• PV=nRT

• P1V1/T1=P2V2/T2

• PT=P1+P2+P3...

A basketball is pumped with air that is composed of three gases: hydrogen, oxygen, and

nitrogen. The three gases have partial pressures of 1.00 atm, 0.29 atm, and 0.99 atm.

What is the total pressure of the gas in the basketball?

• PV=nRT

• P1V1/T2=P2V2/T2

• PT=P1+P2+P3.....
