The Gas Constant (R) In PV = nRT: The gas constant (R) is also known as the universal, molar, or ideal gas constant. This gas constant referred to as a physical constant that is introduced in different fundamental equations in the physical sciences, such as the ideal gas law, the Arrhenius equation, and the Nernst equation.

3. Use the ideal gas law, PV = nRT, to calculate the Gas Constant R. (Assuming O2 is an Ideal Gas) Abstract: A gas is a form of matter that consists of a collection of molecules in chaotic, random motion. Unlike a solid or liquid, the molecules of a gas are widely separated, and a gas will expand or contract to fit the container in which it is
In the equation PV=nRT, the term “R” stands for the universal gas constant. The universal gas constant is a constant of proportionality that relates the energy of a sample of gas to the temperature and molarity of the gas. Values of R (Gas Constant) Value Units (V.P.T −1.n−1) 8.314 4621(75) J K−1 mol−1 5.189 × 1019 eV K−1 mol−1 0.082 057 46(14) L atm K−1 mol−1 1.985 8775(34) cal K−1 mol−1 1.985 8775(34) × 10−3 kcal K−1 mol−1 8.314 4621(75) × 107 erg K−1 mol−1 8.314 4621(75) L kPa K−1 mol−1 The Universal Gas Constant - Ru - appears in the ideal gas law and can be expressed as the product between the Individual Gas Constant - R - for the particular gas - and the Molecular Weight - Mgas - for the gas, and is the same for all ideal or perfect gases: R u = M gas R The Universal Constant defined in Terms of the Boltzmann's Constant The ideal gas constant is the combination of Boyle’s law, Avogadro’s number, Charles’s law and Gay-Lussac’s law.

These tables contain 188 values for the Universal Gas Constant in the most likely combinations of units. These include the most commonly used values for the universal gas constant The R is also known as ideal gas constant or universal gas constant or molar constant. Value Of Gas Constant The value of R at atm that is at standard atmospheric pressure is R = 8.3144598 J.mol -1 .K -1 . Defining the specific gas constant R specific(r) as the ratio R/M, p = ρ R specific T {\displaystyle p=\rho R_{\text{specific}}T} This form of the ideal gas law is very useful because it links pressure, density, and temperature in a unique formula independent of the quantity of the considered gas. The ideal gas constant is nothing more than a conversion factor for units of measure of the gas, and there are many different numerical values.
