Ideal gas law | Definition, Formula, & Facts » Ideal gas law, relation between the pressure P, volume V, and temperature T of a gas in the limit of low pressures and high temperatures, such that the molecules of the gas move almost independently of each other. In such a case, all gases obey an equation of state known as the ideal gas law: PV = Britannica.com

Generalization of Eight Methods for Determining R in the Ideal Gas Law » The ideal gas law of physics and chemistry says that PV = nRT. This law is a statement of the relationship between four variables (P, V, n, and T) that reflect properties of a quantity of gas in a container. The law enables us to make accurate predictions of the value of any one of the four variables from the values of the other three. The symbol R (called the "molar gas constant") is the sole parameter or constant of the law. R stands for a fixed number that has been shown through experiments to equal approximately 8.314472. Eight methods are available to analyze the data from a relevant experiment to determine the value of R. These methods are specific instances of eight general methods that scientists use to determine the value(s) of the parameter(s) of a model equation of a relationship between variables. Parameter estimation is one step in the study of a relationship between variables. Arxiv.org

What does the R stand for in the ideal gas law (PV=nRT)? | Socratic » The units of the universal gas constant R is derived from equation PV = nRT. It stands for Regnault. If the pressure P is in atmospheres (atm), the volume V is in liters (L), the moles n is in moles (mol), and temperature T is in Kelvin (K), then R is in "L"cdot"atm/mol"cdot"K". R has the value "0.082057 L"cdot"atm/mol"cdot"K" with the above units for the remaining variables. In other scenarios with pressures of "bars" instead, you may also use "0.083145 L"cdot"bar/mol"cdot"K". However, temperature must always be in Kelvin (K), as R uses units of "K". There is a variation of the ideal gas law that uses the density of the gas with the equation PM = DRT where M is the molar mass in "g/mol" and D is the density of the gas in "g/L". Lastly, this video may help introduce you to the ideal gas law. I hope this is helpful. Socratic.org
