State-of-the-art vacuum equipment can attain pressures as 3.0 x 10-11 Pa. Suppose that a chamber contains helium at that pressure and at temperature 290 K. Assume the diameter e a helium atom is 1.0 x 10-10 m. 1) Estimate the mean free path for helium in the chamber. (Express your answer to two significant figures.) 10011000
