The gas constant (also known as the molar, universal, or ideal gas constant, normally indicated by the symbol R) is a physical constant which is used in many of the fundamental equations in the physical sciences, such as the ideal gas law and the Nernst equation. It is equivalent to the Boltzmann constant, but expressed in units of energy (i.e. the pressure-volume product) per kelvin per mole (rather than energy per kelvin per particle). The gas constant uses the same units as specific entropy.
Its value is: : R = 8.314472(15) J · K-1 · mol-1The two digits in parentheses are the uncertainty (standard deviation) in the last two digits of the value. The gas constant occurs in the simplest equation of state, the ideal gas law, as follows: : PV = nRT = nRT / V = RT / Vm
where: : P: is the absolute pressure : T: is absolute temperature : V: is the volume the gas occupies : n: is the amount of gas (the number of gas molecules, usually in moles) : Vm: is the molar volume

What is the difference between universal gas constant and characteristic 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...
Is universal gas constant equal Avogadro constant?
of course. that's why it's called the universal gas constant.
Is universal gas constant equal equilibrium constant?
No
What is the ideal gas constant?
It is a universal constant used for all gases.
What the value of the universal constant?
There are several different universal constants: Avogadro's number, Gas constant, Gravitational constant. The question needs to be more specific.
The correct value for the universal gas constant is what?
.0821
What is constant for 1 mole of any ideal gas?
The Universal Gas Constant is 8.314 J/K/Mole
What is the ideal gas?
It is a universal constant used for all gases.
How does the molar concentration at Standard temperature and pressure depend upon the identity of the gas?
Molar concentration is defined as the amount of a gas divided by the volume of gas. According to the gas identity, at standard temperature and pressure, even if the amount of the gas is constant, the volume of gas changes. Thus, the molar concentration changes depending on the gas identity.
How do you use the universal gas constant?
The Universal Gas constant can be used to relate the volume, temperature, pressure, and quantity of a gass to each other. The relationship is PV=nRT, or the pressure times the volume equals the number of moles times the universal gass constant times the temperature.
What is the constant for 1 mole of any ideal gas?
The Universal Gas Constant is 8.314 J/K/Mole
What is the value and units of the molar gas constant?
R = 0.082 ATM L/mol K
