What is the value of R, the gas constant?

What is the value of the gas constant of helium ?

  • I am looking for the R value in KPa.m^3/kg.k

  • Answer:

    The ideal gas constant R is independent of the compound, so it's R = 8.314 J/mol K. Helium, with it's small size (and thus low collision radius) and very low electrical interaction (thanks to is filled valence shell), is probably the closest that you are going to get to an ideal gas.

Divide the molecular weight of Helium (4.003 g/mol) into R, the universal gas constant, which is equal to 8.31447 Pa m^3/K/mol.
