Question

Physics

An extremely small sample of an ideal diatomic gas (with a molarmass of 28 g/mol) has the following distribution of molecularspeeds: 1 molecule moving at 100 m/s, 2 molecules at 200 m/s, 4 at300 m/s, and 3 at 400 m/s.

What is the rms speed of the distribution? What is the averagekinetic energy of translational motion per molecule? What is thetemperature of this sample?
