$50.($a$)$ Hydrogen molecules $($molar mass is equal to $2\mathrm{.}016$ g$/$mol$)$ have equal to $193$ m$/$s$.$ What is the temperature? $($b$)$ Much of the gas near the Sun is atomic hydrogen $($H rather than Its temperature would have to be for the rms speed to equal the escape velocity from the Sun. What is that velocity?
