Calculate the thermal velocity for Carbon dioxide gas (CO2: mass = 7.35 x 10-26 kg), Hydrogen (H2: mass = 3.33 x 10-27 kg) and for water vapor (H2O: mass = 3.0 x 10-26 kg) for the exosphere of Venus where the temperature is 350K.

Thanks for the opportunity to answer your question!

Thermal Velocity = 5.25 x 10^{-12} (T/m_{part})^{1/2}

Carbon Dioxide: 5.25 x 10^{-12} (350K/7.35 x 10^{-26}kg)^{1/2}

0.00000000000525 * (350K/7.35 x 10^{-26}kg)^{1/2}

0.00000000000525 * 69006555934235.42

= 362.28 m/s

Hydrogen: 5.25 x 10^{-12} (350K/3.33 x 10^{-27}kg)^{1/2}

0.00000000000525 * (350K/3.33 x 10^{-27}kg)^{1/2}

0.00000000000525 * 324199175053091.56

= 1702.05 m/s

Water Vapor: 5.25 x 10^{-12} (350K/3.0 x 10^{-26}kg)^{1/2}

0.00000000000525 * (350K/3.0 x 10^{-26}kg)^{1/2}

0.00000000000525 * 108012344973464.33

= 567.06 m/s
