The molecules of a certain gas sample at 367 K have a root-mean-square (rms) speed of 261 m/s. Calculate the most probable speed and the mass of a molecule.

  • Chemistry Help -

    rms = sqrt(3kT/m)
    k is the Boltzman constant (look that up)
    T is given in kelvin.
    m is the mass of 1 molecule. Solve for that.
    The average speed is (rms)^2
