Finding the Pressure inside a lighter

[Tugberk]

Homework Statement

I need to do an experiment to verify the gas constant R and I can only use a lighter. The equation useful is PV=nRT but I don't know how I can find the pressure inside the lighter. Any help is appreciated! :D

Homework Equations

I don't know what other equation might be used other than PV=nRT

You may be able to use combined gas law to solve this. Does you experimental design allow for the construction of a manometer?

There is no need to measure the pressure inside the lighter. Besides, it won't help, as the gas inside is in a liquid form, so it doesn't obey the ideal gas law.

Yeah that's right, but I found a way to do it so it's all good now :)
