Ideal Gas Law

Static Gas Conditions Ideal gas law shows the relationship between pressure, volume, temperature, and number of moles in a gas If you know any three variables, you can find the fourth

PV = nRT P – pressure (in atm) V – volume (in L) n – number of moles T – temperature (in K) R – Ideal Gas Constant = .0821 L atm/ mol K
