When is pv=nrt used? [ENDORSED]

[Madelyn Cearlock]

Can someone please explain to me when the ideal gas law is used?

[Timothy_Yueh_4L]

You would use the ideal gas law if the question gave you a both concentration and pressure values which you would use to convert all the values to either concentration or pressure to solve for the equilibrium constant.

[Isabelle Fontanilla 1I]

Also, the constants sheet should have the gas constant, R, on it. For this, use the most appropriate form so you will have common units. As for temperature, T, it should be given in the problem. Like the previous answer stated, use the Ideal Gas Law to convert between concentration and partial pressure.

and the concentration is the number of moles over the volume

[Rachel Yoo 1F]

You can use PV=NRT in any situation when given any three out of the four: pressure, volume, number of moles, or temperature. R=.08206. In this instance, we use it to convert Kc to Kp or vice versa

You can use this equation to find an unknown (pressure, volume, molarity or temp)
