Rubber balloons filled with helium do not last as long as those filled with nitrogen or air for the reason that the helium leaks out in a day or two through tiny holes in the rubber, while the rate of effusion of nitrogen through the holes is much slower. If a balloon is filled with 48% helium as well as 52% nitrogen (by volume), Explain what is the percentage of He in the gas leaking out through the rubber?
