What is the visosity of gases?

We will not use the term viscosity for gases instead we use the term diffusion rate through a small orifice, which is inversely related to squire root of molecular mass and directly related to squire root of absolute temperature. Or it is related to RMS velocity of gas molecules. For example if you fill one balloon with hydrogen gas and another with air, we can see that the size of hydrogen balloon reduces more if you observe the size after 6 to 8 hours. It is due to the fact that hydrogen diffuse faster through smaller pores of the balloon.
