### Determining N

In PV = NRT, what moles are accounted for and which are excluded? (Do aqueous contributions also get excluded?)

It's the ideal gas law so you just use it for gases.

You can only use pvnrt for gases, so in the calculations, use the moles of gas.

Only moles of gas are accounted for because it is the ideal gas law.

You should only use it for calculating the moles of gases.

### Re: Determining N

N is determined by the moles of gas, or put more simply, the concentration.

PV = nRT is the Ideal Gas Constant, so it applies to gases, not aqueous solutions.

### Re: Determining N

The "n" here is in the ideal gas equation, therefore you should plug in the moles of gas.

### Re: Determining N

Since we are talking about the ideal gas equation the n would be moles of our gas
