Can someone tell me what gas law equation I'd use for any type of gas law problem? (ex. if the pressure and temperature is given, you'd use _____ law.)

ex. Boyle's law, Charles' law, ideal gas law, etc.

Boyle's law is for Pressure and Volume

P1V1=P2V2 (pretend the numbers are subscripts)

Charles' law uses Volume and Temperature.

V1 over T1 = V2 over T2

Combined Gas Law uses pressure, volume, and temperature.

P1V1 over T1 = P2V2 over T2

Avogadro's Law uses Volume and the Number of Moles

V1 over n1 = V2 over n2

The Ideal Gas law uses:

Pressure, Volume, Number of moles, The Gas Constant*, and the temperature.

The Gas Constant is .08206. The Label for this is L x atms over Mol x K.

The equation is PV=nRT.

Remember, temperature should always be in Kelvin (k).

Good Luck =)
