What is L atm mol K?
Where the pressure – P, is in atmospheres (atm) the volume – V, is in liters (L) the moles -n, are in moles (m) and Temperature -T is in Kelvin (K) as in all gas law calculations. Pressure and Temperature must remain in the units atm and K and the Gas Law Constant remains R = 0.0821 (atm) L / (mol) K.
What is R in kJ mol K?
R. 8.3145. J/K·mol. ideal gas constant. R.
How do you find the gas constant?
The specific gas constant Rs varies per different gases and mixtures. It can be written mathematically as: Rs = R / M , where M is the molar mass of the gas or mixture.
What is the gas constant in ATM?
0.0821 atm
P = Pressure (atm) V = Volume (L) n = moles R = gas constant = 0.0821 atm•L/mol•K T = Temperature (Kelvin) The correct units are essential.

What is the value of gas constant in SI unit?
R is known as the universal gas constant =8.3145J/mol. K. The value of the gas constant ′R′ depends on the units used for pressure, volume and temperature. When we use the gas constant R = 8.31 J/K.
What is the gas constant called?
The gas constant is a physical constant denoted by R and is expressed in terms of units of energy per temperature increment per mole. It is also known as Ideal gas constant or molar gas constant or universal gas constant.
What is the universal gas constant ru?
The universal gas constant(Ru) is, as its name implies, universal, i.e., the same regardless of the gas being considered. The ideal gas lawin terms of Ruis PnRTVu, where Pis the absolute pressure of the gas, Vis the volume occupied by the gas, nis the number of mols of the gas, and Tis the absolute temperature of the gas.
