Calculating the r value in universal

Specific gas constant the specific gas constant (r, sometimes rgas) is not universal, and its value depends on the specific gas being considered r is defined as the universal gas constant divided by the molecular weight of the substance, u r r m the dimensions of r are not the same as those of ru, since molecular weight is a not a dimensionless.
