Solve.The process by which a gas escapes from a container with a small puncture is called "effusion". Under identical conditions, gases with relatively small particle masses effuse more rapidly than gases with larger particle masses. The relative rate of effusion of helium (He) and nitrogen (N2) can be computed using: relative rate = 
= 
,where MHe is the mass of the helium particles and MN2 is the mass of the nitrogen particles. Assuming MHe = 4 and MN2 = 28 (arbitrary units), find the exact value of the relative rate of effusion.
