A laboratory vacuum pump can generate a vacuum of about 1 nTorr at 27°C. Assuming that air consists of N2 molecules with a collision diameter of 395 pm, calculate (a) the mean speed of the molecules, (b) the mean free path, (c) the collision frequency in the gas. Given that Boltzmann constant 1.38×10−23 J⋅K −1, nano refers to 10-9 and Pico refers to 10-12, 1 torr = 133.22 Pascals, molar mass of nitrogen is 14.01 g/mo
