Problem

A research team investigates the transport properties of neon isotopes at 350 K. Two separate rigid containers hold pure samples of

^{20}\text{Ne}

(molar mass = 19.99 g mol

^{-1}

) and

^{22}\text{Ne}

(molar mass = 21.99 g mol

^{-1}

), each at 1.00 atm. (1) Part 1: (a) Determine the rms speed of a

^{20}\text{Ne}

atom at 350 K. (2) Part 2: (b) Determine the rms speed of a

^{22}\text{Ne}

atom at the same temperature. (3) Part 3: (c) Calculate the percentage difference between the rms speeds of the two isotopes and interpret what this implies about their relative diffusion rates under identical conditions.
