5. The diameter d for an O2 molecule is 0.36
nm. The molar mass is 32.0 g mol-1.
(a) calculate the root mean squared speed
of an 02 molecule at 298 K.
(b) if the pressure is 1.0 bar inside a balloon
containing oxygen gas, calculate the
number of collisions per second
experienced by an oxygen molecule at
298K.
(c) calculate the mean free path of the 02
molecule at 298 K and 1 atm.
