Answer:

For a given force (as determined by the elastic modulus), "light" molecules can oscillate at a greater frequency than "heavy" molecules; so a less dense medium will have a higher frequency per wavelength (i.e. a higher wave speed) than a more dense medium. The speed of sound in air is 332m/s.
