WebExplanation: The value of R is 0.0821 dm3.It means that if we have one mole of an ideal gas at 273.16 K and one atmospheric pressure and it’s temperature is increased by 1K then it will absorb 0.0821 dm3-atm of energy. …. Hence R is called the universal gas constant. WebThe induvidual gas constant, R, for a gas can be calculated from the universal gas constant, R u ( given in several units below ), and the gas molecular weight, M gas: R = R u /M gas [1] In the imperial system the most common units for the individual gas constant are ft lb/slug oR. In the SI system the most common units are J/kg K .
