The mean free path of an oxygen molecule is [l] m, when the gas is at a pressure of [p] Pa and a temperature of [t] K. The molar mass of oxygen is 32.0 g/mol. Assuming that the molecules are moving at their root-mean-square speeds, what is the average time interval between collisions of an oxygen molecule in nanoseconds? 1 ns = 10-9 s Boltzmann constant = 1.38 × 10-23 J/K Avogadro’s number = 6.02 × 1023 molecules/mole R = 8.314 J/mol · K = 0.0821 L · atm/mol · K.  Enter only a numerical value (3 sig. fig) without units.
