The molar gas constant (R), expreseed in J/mol.K, has a value (after IUPAP and IUPAC tables) of 8,314 472 ± 0,000 015.
The relative standard uncertainty is 1,70.
of course. that's why it's called the universal gas constant.
The Universal gas constant is R is independent of the gas taken.. While the Characteristic gas constant depends on the mol. mass of the gas.... The Characteristic gas constant of a gas or a mixture of gases is given by the molar gas constant, divided by the molar mass (M) of the gas/mixture. R(Characteristic) = {R}/{M} Well,this is just the basic...u can relate them both to the Boltzmann constant.. Here are some of the standard values for both: Values of R Units 8.314 472(15) J K−1 mol−1 0.082057 46(14) L atm K−1 mol−1 RChar for dry air Units 287.058 J kg−1 K−1 ok,i guess this is it!Hope this clears it...
The constant k in Charles's law, which relates the volume and temperature of a gas, would not vary with different masses of trapped gas. The constant k is determined by the gas itself and remains constant as long as the pressure of the gas is held constant. Changing the mass of the gas would affect the pressure and density of the gas, but not the constant k in Charles's law.

The gas constant is the same for all gases: R = 8,314 462 1(75) J/mol.K
R may be the Rydberg constant or the gas constant.
No, mole percent and volume percent are not necessarily equal for a gas. Mole percent is the ratio of the moles of a gas to the total moles of all gases in a mixture, while volume percent is the ratio of the volume of a gas to the total volume of all gases in a mixture. The two can be equal only if the gases have the same molar volume at the given conditions.
No, the gas constant, or any constant, is constant meaning it doesn't change.
Combined gas law states:" The ratio between the pressure-volume product and the temperature of a system remains constant: p.V = k.T "k is a constant which only is proportionally depending on the amount of gas.
of course. that's why it's called the universal gas constant.
If the temperature of a gas is reduced by 25%, its volume decreases proportionally if the pressure and quantity of gas remain constant. This is known as Charles's Law, which states that the volume of a gas is directly proportional to its absolute temperature.
Boltzmanns constant
The percent amount of nitrogen in the air remains constant because nitrogen gas is a non-reactive gas and does not easily participate in chemical reactions that would alter its composition in the atmosphere. This stability allows the nitrogen component to remain consistently at around 78% of the Earth's atmosphere.
"Characteristic Gas Constant"The constant 'R' used in the characteristic gas equation PV=RT , has a constant value for a particular gas and is called 'Characteristic gas constant' or 'specific gas constant' . Its value depend upon the temperature scale used and the properties of the gas, under consideration.The value of R will be.For atmospheric pressure air,R= 287 J/kg/k
The constant motions allow the gas to fill whatever contains it.
