### Jupiter's exosphere has a temperature of about 840.0 K. What is the thermal speed of hydrogen (in km/s) in Jupiter's exosphere? The mass of a hydrogen atom is 1.67 x 10^-27 kg and Boltzmann's constant is k = 1.38 × 10^-23 Joule/Kelvin. I need help with this I don't understand. I get this is the formula: (Thermal Speed)^2 = 2 · Boltzman constant · Temperature / Mass But I am getting it wrong.
