Root mean square speed of an unknown gas
WebVery few molecules move at either very low or very high speeds. The number of molecules with intermediate speeds increases rapidly up to a maximum, which is the most probable speed, then drops off rapidly. Note that the most probable speed, ν p, is a little less than 400 m/s, while the root mean square speed, u rms, is closer to 500 m/s. WebAn unknown gas (empirical formula CH4N) has a root-mean-square speed of 353 m/s at 300K. Calculate the molecular formula of the gas.
